  [MC][NFC] Make ELFUniquingMap a StringMap (#95006)

This avoid std::map, which is slow, and uses a StringMap. Section name,
group name, linked-to name and unique id are encoded into the key for
fast lookup.

This gives a measurable performance boost (>3%) for applications that
compile many small object files (e.g., functions in JIT compilers).

  [msan][NFC] Make mask in test more interesting (#94874)

Low 4 and high 4 bits of mask have a different purpose.

Irrelevant for the current implementation, but
will be used in the followup patches.
