[clang-tools-extra] [clangd][modules] Remove the options when driver detects that it was unsupported, and log them (PR #200001)

https://github.com/ArcsinX requested changes to this pull request.

We also need a test for this.
These changes are not directly related to modules anymore, we just skip unknown options from the command line in the command mangler, so we can add a unit test into CompileCommandsTests.cpp
