Parse the section specifier indicated by "Spec".

ParseSectionSpecifier - Parse the section specifier indicated by "Spec".

This is a string that can appear after a .section directive in a mach-o flavored .s file. If successful, this fills in the specified Out parameters and returns an empty string. When an invalid section specifier is present, this returns an Error indicating the problem. If no TAA was parsed, TAA is not altered, and TAAWasSet becomes false.
