Subject: [PATCH 1/2] [GitHub] Add CI for libclang Python unit tests

* Run on all pull requests and direct pushes.
* This makes use of the existing llvm-project-tests.yml
  recipe, which will preload ccache from previous runs.
* Building libclang currently takes about 9mins when
  ccache is warm and about an 1hr 20mins if it is cold
  using the standard GitHub ubuntu runner.
* This could be broken into the following two steps:
  - # Build libclang dependency.
    ninja -C build libclang
  - # Run Python unit tests.
    ninja -C build check-clang-python

Issue #76601.

Subject: [PATCH 2/2] [GitHub] Remove libclang Python actions fork protection

Remove the check that only allows the action to run if
it is running from the parent llvm organization repo.
This is meant to protect contributors that fork the
project from automatically launching actions with their
account quota.

This shouldn't be necessary, since GitHub Actions are
disabled automatically on forks. The following docs says
"When a public repository is forked, scheduled workflows
are disabled by default.".

https://docs.github.com/en/actions/using-workflows/disabling-and-enabling-a-workflow
