[Parser] Use special definition for pragma annotations

Previously pragma annotation tokens were described as any other
annotations in TokenKinds.def. This change introduces special macro
PRAGMA_ANNOTATION for the pragma descriptions. It allows implementing
checks that deal with pragma annotations only.
