[MC] Replace MCContext::GenericSectionID with MCSection::NonUniqueID (#126202)

They have same semantics. NonUniqueID is more friendly for isUnique
implementation in MCSectionELF.

History: 97837b7 added support for unique IDs in sections and added
GenericSectionID. Later, 1dc16c7 added NonUniqueID.
