fix(lsp/roslyn): skip semantictokens/full for razor/cshtml

Roslyn's full semantic tokens request is now bypassed for .razor and .cshtml
files, preventing issues with cohosted Razor where semantictokens/full are
not supported. This avoids unnecessary or problematic LSP requests for
these file types.
