Prepare the docs for using the notation used in the `python.gram`
file. If we want to sync the two, the meta-syntax should be the same.
Link the Full Grammar docs here; keep only a few extras.
Also, remove the distinction between lexical and syntactic rules,
except for whitespace handling.
With f- and t-strings, the line between the two is blurry.

The `test_ssl_in_multiple_threads` test failed because `test_check_hostname_idn()`
modified the global warnings filters via `warnings_helper.check_no_resource_warning()`.
Only check for warnings when the context aware warnings feature is enabled, which makes
the warnings filter context-local and thread-safe.

On Windows, the `_PyOS_SigintEvent()` event handle is used to interrupt
the main thread when Ctrl-C is pressed. Previously, we also waited on
the event from other threads, but ignored the result. However, this can
race with interpreter shutdown because the main thread closes the handle
in `_PySignal_Fini` and threads may still be running and using mutexes
during interpreter shtudown.
Only use `_PyOS_SigintEvent()` in the main thread in parking_lot.c, like
we do in other places in the CPython codebase.

gh-134248 test_getallocatedblocks pre-check to ignore immortalized strings (GH-134871)
