Add pragma errors for malformed pragmas.

Instead of always warning on invalid pragmas, only warn when the pragma
type is not recognized and error when the syntax is invalid.

Fixes:
dEQP-GLES2.functional.shaders.preprocessor.pragmas.invalid_pragma_invalid_debug_vertex
dEQP-GLES2.functional.shaders.preprocessor.pragmas.invalid_pragma_invalid_debug_fragment
dEQP-GLES2.functional.shaders.preprocessor.pragmas.invalid_pragma_invalid_token_vertex
dEQP-GLES2.functional.shaders.preprocessor.pragmas.invalid_pragma_invalid_token_fragment
