a00efe55c3 Fix CheckOutputStreamSetting on JitLoggingTest as it failed if logging wasn't enabled. (#82722)
`JIT_LOG` checks if logging was enabled for that particular file and when it isn't it doesn't output anything. Since the test checks for the size of `test_stream` it fails. I believe forcing the file to have logging enabled to see if the stream is being correctly set during test makes no sense so this patches just forcibly outputs and checks if it worked.

2828ce53fd Added jit log stream changing function and some refactor (#65768)
Summary:
Description:
- Have only added `stdout` and `stderr` as possible options from python
  API for now. We can do file path passing later maybe.
- Put the class `JitLoggingConfig` in the cpp file as none of its methods were being used outside of this file.

Python API:
`torch._C._jit_set_logging_stream('stdout|stderr')`
C++ API:
`::torch::jit::set_jit_logging_output_stream(ostream);`

Testing:
- Tested python API locally.
- Unit test for the C++ API is written

9d1d799034 Added API to change logging levels for JIT (#58821)
Summary:
Description:
- Before this, logging level could only be changed by changing the env
variable "PYTORCH_JIT_LOG_LEVEL"
    - Can change the level from python now
- Have not added stream configuration for now
- Configuration is stored in a singleton class managing the options

Issue Link: https://github.com/pytorch/pytorch/issues/54188

Gotchas:
- Created separate functions
`::torch::jit::get_jit_logging_levels/set_jit_logging_levels` instead of
using the singleton class's method directly
    - This is because when running test cases, two different instances
    of the singleton are created for the test suite and the actual code
    (`jit_log.cpp`)
    - On using these methods directly, `is_enabled` calls the singleton
    in `jit_log.cpp` while we are setting the config using another
    singleton
    - See: https://stackoverflow.com/questions/55467246/my-singleton-can-be-called-multiple-times

API:
- To set the level: `torch._C._jit_set_logging_option("level")`
- To get the level: `torch._C._jit_get_logging_option()`

Testing:
- UTs were added for C++
- A very simple UT was added for python to just check if the API is
being called correctly
- The API was checked by running trace in a sample python file
    - Set env variable to "" and used `_jit_set_logging_option` in python to set the variable to `>dead_code_elimination`
    - The error output had logs of form [DUMP..] [UPDATE...] etc
