mesa: recognize enums GL_COLOR_ATTACHMENT8-31 as valid

Similar as for AUX1-3, these enums aren't invalid (i.e. -1) but also not
supported by mesa. Returning BUFFER_COUNT causes the proper error to be
returned by ReadBuffer and other functions. This resolves some failures
in

dEQP-GLES31.functional.debug.negative_coverage.get_error.buffer.read_buffer
