[clangd] Disable backend-releated filelist compiler options.
These options doesn't affect the AST generation, and clang will crash (CreateOrDie in ASTContext) immedidately when the provided file are not existed. Disable them in clangd to make clangd more robust. Differential Revision: https://reviews.llvm.org/D140960
