glsl: Drop the round-trip through ast_type_specifier for many builtin types.

Browse Source 
We have lexer recognition of a bunch of our types based on the
handling.  This code was mapping those recognized tokens to an enum
and then to a string of their name.  Just drop the enums and provide
the string directly in the parser.
