It's already a requirement for building PyTorch, but should be a
requirement for linking extensions with it, as that can lead to runtime
crashes, as `std::optional` template layout is incompatible between
gcc-9 and older compilers.
Also, update minimum supported clang version to 9.x(used to build Android), as clang-5 is clearly not C++17 compliant.

To avoid new contributor issues when building master a couple README.md comments will help... This change:
~~- Documents the current support restriction to apt package `g++-9` #91328 ** noting here that with the commit in https://github.com/pytorch/pytorch/pull/92911 g++-11.3 appears to build and run local tests at least as well as g++9, so this restriction may be overcome with that PR merge depending on success and CI updates.~~ (fixed now)
- Documents wip status for CUDA 12 #91122 (by forwarding to support matrix per suggestion)

Update release related information. Features became more complex. Number of commits per releases have increased a lot.
We had in average:
2.5k commits for releases 1.1.0-1.7.0,
3-3.5k commits for releases 1.8.0-1.12.0
4.5k-5k commits for releases 1.13.0, 2.0.0
Hence current target is 3 releases a year

Mostly `s/@master/@main` in numerous `.yml` files.
Keep `master` in `weekly.yml` as it refers to `xla` repo and in `test_trymerge.py` as it refers to a branch PR originates from.
The `requirement.txt` file is in the PyTorch directory. The instructions to `clone` and `cd` to the PyTorch directory are in the later section under Get the PyTorch Source. So, the instructions as such gives an error that requirement.txt is not found.
```ERROR: Could not open requirements file: .. No such file or directory: 'requirements.txt' ```
This PR clarifies the usage of the command.

## `pip install -r requirements.txt` in build-from-source documentation
This line
81b5eff3c3/README.md (L182-L188)
Is outdated. Let's default to `requirements.txt`
### My problem
Without touching this codebase for years I'm trying to build repo for local development and run unit tests. I go to `build from source => Contributing.md`. I immediately run into various problems.
* [Contributing.md](https://github.com/pytorch/pytorch/blob/master/CONTRIBUTING.md#developing-pytorch) suggests one way of setting up environment different from [README.md#from-source](https://github.com/pytorch/pytorch/blob/master/README.md#from-source) that does not work for me.
* [README.md#from-source](https://github.com/pytorch/pytorch/blob/master/README.md#from-source) suggests a different set of dependencies than [`requirements.txt`](https://github.com/pytorch/pytorch/blob/master/requirements.txt), many of which are unnecessary, and there's still missing ones to run unit tests.
* Dependencies in `requirements.txt` are needed to run unit tests
So there's competing, inlined and outdated equally confident recommendations on how to set up. https://github.com/pytorch/pytorch/pull/91850 tries to remove one recommendation, this PR tries to make the default one simpler.
### Goals
* Improve society somewhat 😁
* Remove a dead end roundtrip in the developer onboarding funnel
* Update a duplicated & outdated line of documentation
* Two broken things => one broken thing
* Improve doc maintainability and nudge us to a productive discussion of what `requirements.txt` is there for.
### Non-goals
* Give a definite recommendation how to set up your machine for local development. I read the instructions in readme at this moment as an outline on how to do it.
* Say that `requirements.txt` is a definite guide to dependencies, I know it's not (but probably should be)
### Background
* Dependency handling/reproducibility in this repo is tricky! See geist of [this](fdbbd20f32/.github/requirements/README.md). There's many different sets of dependencies with different setups for different environments.
* There's been great attempts of _"one requirements.txt to rule them all"_ which got halted https://github.com/pytorch/pytorch/pull/60697/ see https://github.com/pytorch/pytorch/issues/61375
* The unofficial `requirements.txt` file seem to be .circleci/docker/requirements-ci.txt https://github.com/pytorch/pytorch/issues/72556
* Unofficial _"how to build from source"_ docs seem to be here https://github.com/pytorch/pytorch/tree/master/.circleci#how-to-build-a-binary-locally
### Considered alternatives
* a) Point only to python dependencies in `requirements.txt` **(Chosen option)**
```
conda install cmake ninja
pip install -r requirements.txt
```
This guarantees `python setup.py` to run (on my machine) and gets me one step closer to be able to `python test/run_test.py`
* b) Only add whats needed to `python setup.py install`. Point to `Contributing.md` for explanations on how to run tests (which doesn't exactly mention how yet).
```
conda create -n pytorch-source python cmake ninja pyyaml typing_extensions
conda activate pytorch-source
python setup.py develop
```
* c) Add dependencies needed to run (most) unit tests
I assume _"Install from source"_ describes how to "install so I can do development.". This is why we recommend `python setup.py develop`. Doing development implies running unit tests.
```
conda create -n pytorch-source python cmake ninja pytest click
conda activate pytorch-source
pip install -r requirements.txt xdoctest
python setup.py develop
python test/run_test.py --keep-going
```
This still eclectically goes outside the simple principle _"Use dependencies in requirements.txt"_ without solving the whole problem. Instructions to get tests to run is not the goal of this PR.
* d) Point to ex [`.circleci/docker/requirements-ci.txt`](https://github.com/pytorch/pytorch/blob/master/.circleci/docker/requirements-ci.txt) or any of the system-specific sets of pinned requirements like [`requirements-{conda-env-macOS-ARM64}.txt`](https://github.com/pytorch/pytorch/blob/master/.github/requirements/conda-env-macOS-ARM64)
I don't want to jump into this rabbit hole.

The main changes are:
1. Remove outdated checks for old compiler versions because they can't support C++17.
2. Remove outdated CMake checks because it now requires 3.18.
3. Remove outdated CUDA checks because we are moving to CUDA 11.
Almost all changes are in CMake files for easy audition.

If someone is building the project from source they're likely a contributor for which develop will be much more useful. For people that want to try the latest and greatest they can leverage the nightlies

Fixes various friction points with the documentation for onboarding new users and remove instructions that were no longer valid
Changes include:
- Listing prerequisites earlier, so that devs can ensure they're met before encountering error messages
- Removing linter invocations that are no longer valid
- Modifying instructions to install mkl packages to only apply to x86 based CPUs

Summary:
This changes the link for installing binaries to the page on pytorch.org that is entirely the download command selector (which isn't visible on a normal aspect ratio screen when the main website page first loads anymore).
This also includes some other random fixes:
* Update HUD link
* Clean ups
