[clangd] Filter pch related flags coming from the user
Summary:
PCH format is unstable, hence using a preamble built with a different
version of clang (or even worse, a different compiler) might result in
unexpected behaviour.
PCH creation on the other hand is something clangd wouldn't want to perform, as
it doesn't generate any output files.
This patch makes sure clangd drops any PCH related compile commands after
parsing the command line args.
