This modifies the config system, to use a single mapping of config ->
ConfigEntry and to store the default and user values within them.
We could have used multiple dicts (i.e. user_override and default), but
as we add more fields (justknobs in this PR, perhaps testing and env
variables later), it quickly becomes painful.
There are a couple design decisions we could change.
1) All configs we save store the resolved value - not the default and
user override seperately
2) All configs we load, apply the resolved value as a user override.
This means that certain complexities of default behvaiour and deletion
(as well as JK), will change if you save + load a config.

This PR combines a number of cleanups in one PR. If any of the specific cleanups don't seem to make sense, let me know and I can remove them.
Cleanups
- This PR adds a set of test suites for the config module code, which handles basically all the APIs and ways it is used. Please let me know if you see anything critical that is not tested that I missed. This test suite is primarily used as the regression test suite for later changes in this diff. Note that there is some dynamo specific testing of the config module, but it isn't as verbose.
- I removed all internal usage of shallow_copy_dict. Those usages could all use the deep copy, and did not depend on the reference behavior of certain config values that shallow_copy_dict allows.
- I removed shallow copy semantics for configuration with a deprecation warning. I think this requires a release note, so hopefully I did that correctly. Let me know if we want to continue to expose shallow copy value semantics, but I just can't find a case where I expect anyone would want it. It also complicated later internal changes to the API (i.e. breaking apart various layers of the config changes).
- I fixed what I believe is a bug in how hashes are calculated on configs. In particular, if you got the hash, then made a config change, and then got the hash again, it would not update the hash. @oulgen, please let me know if I'm misunderstanding this behavior and it is desired.
- I switched our multiple implementations of iterating through the dictionary to a single one. This is primarily to make later changes easier, but it also makes it clear how inconsistent our various config ignoring options are. Let me know if people would be interested in me unifying the various options for ignoring config values.
- I updated the test patcher (not the performance critical one, just the normal one), to use __setattr__ and __getattr__ to remove direct API access to the underlying config fetcher.
For release notes, Not sure exactly how to communicate this, but something like
"ConfigModule.to_dict, and ConfigModule.shallow_copy_dict no longer retain their shallow copy semantics, which allowed reference values objects to be modified. If you wish to modify the config object, call load_config explicitly".

Before, having arbitrary depth nested configs like
```
class Foo:
foo: List[int] = [1, 2, 3]
class Bar:
bar: str = "1"
class Baz:
baz: int = 1
```
would cause problems beyond the first layer. For example, if we tried
```
from torch._inductor import config as inductor_config
print(inductor_config.Foo)
print(repr(inductor_config.Foo.foo))
print(inductor_config.Foo.Bar)
print(repr(inductor_config.Foo.Bar.bar))
print(inductor_config.Foo.Bar.Baz)
print(repr(inductor_config.Foo.Bar.Baz.baz))
```
we would get some output like
```
<torch.utils._config_module.SubConfigProxy object at 0x7fac65de00a0>
[1, 2, 3]
...
AttributeError: torch._inductor.config.Foo.Bar does not exist
```
Obviously, this is not what we want. With these changes, we get the right values
```
<torch.utils._config_module.SubConfigProxy object at 0x7f840d05bf40>
[1, 2, 3]
<torch.utils._config_module.SubConfigProxy object at 0x7f840cedc940>
'1'
<torch.utils._config_module.SubConfigProxy object at 0x7f840cedc100>
1
```

- More conservative estimation of plannable inputs
- Consider constant_pad_nd as pointwise node in concat lowering
- Use aten.cat instead of constant pad ndwhen padding just a single dimension because it can be memory-planned away

Use `typing_extensions.deprecated` for deprecation annotation if possible. Otherwise, add `category=FutureWarning` to `warnings.warn("message")` if the category is missing.
Note that only warnings that their messages contain `[Dd]eprecat(ed|ion)` are updated in this PR.

`install_config_module` makes a regular module into a ConfigModule with
extra methods defined on it. mypy thinks those extra methods (or module
functions) are undefined since it cannot analyze something so
dynamic. As a workaround, I've created a fake module that defines these
extra functions, which I import into the config modules during type
checking.
As part of this change, I've also added more types to config_utils.py
and enabled typechecking for torch/_dynamo/config.py.
