[Github] Remove call to llvm-project-tests from libclang tests

[boomanaiden154]

This allows for removing llvm-project-tests.yml. This significantly
reduces the complexity of this workflow (including the complexity of
llvm-project-tests.yml) at the cost of a little bit of duplication with
the other workflows that were also using llvm-project-tests.yml.

Sounds good. A few comments:

Please also remove the .github/workflows/llvm-project-tests.yml entry under
on.push.paths & on.pull_request.paths in the workflow file.
