[clang][modules] Strip LLVM options (llvm#75405)
Currently, the dep scanner does not remove LLVM options from the argument list. Since LLVM options shouldn't affect the AST, it is safe to remove them all. (cherry picked from commit e007551) Conflicts: clang/lib/Tooling/DependencyScanning/ModuleDepCollector.cpp
