[lld-macho] Optimize bind opcodes with multiple passes

In D105866, we used an intermediate container to store a list of opcodes. Here,
we use that data structure to help us perform optimization passes that would allow
a more efficient encoding of bind opcodes. Currently, the functionality mirrors the
optimization pass {1,2} done in ld64 for bind opcodes under optimization gate
to prevent slight regressions.
