## Summary

This PR stabilizes the preview behavior introduced in
#15719 to recognize all symbols
named `TYPE_CHECKING` as type-checking
checks in `if TYPE_CHECKING` conditions. This ensures compatibility with
mypy and pyright.

This PR also stabilizes the new behavior that removes `if 0:` and `if
False` to be no longer considered type checking blocks.
Since then, this syntax has been removed from the typing spec and was
only used for Python modules that don't have a `typing` module
([comment](#15719 (comment))).

The preview behavior was first released with Ruff 0.9.5 (6th of
February), which was about a month ago. There are no open issues or PRs
for the changed behavior


## Test Plan

The snapshots for `SIM108` change because `SIM108` ignored type checking
blocks but it can no
simplify `if 0` or `if False` blocks again because they're no longer
considered type checking blocks.

The changes in the `TC005` snapshot or only due to that `if 0` and `if
False` are no longer recognized as type checking blocks

<!-- How was it tested? -->
