[clangd] More precisely enable clang warnings through ClangTidy options
clang-tidy's behavior is to add the -W flags, and then map all clang diagnostics to "clang-diagnostic-foo" pseudo-check-names, then use Checks to filter those. Previous to this patch, we were handling -W flags but not filtering the diagnostics, assuming both sets of information encoded the same thing. However this intersection is nontrivial when diagnostic group hierarchy is involved. e.g. -Wunused + clang-diagnostic-unused-function should not enable unused label warnings. This patch more closely emulates clang-tidy's behavior, while not going to the extreme of generating tidy check names for all clang diagnostics and filtering them with regexes.
