Clangd used first token of filename as filename range rather than the
synthezied filename token. Unfortunately the former only contains `"` or `<` in
the raw lexing mode, resulting in wrong range information and breaking tidy
checks that relied on it.

Fixes https://github.com/clangd/clangd/issues/896.
