[BOLT] Fix NOP instruction emission on x86 (#72186)
Use MCAsmBackend::writeNopData() interface to emit NOP instructions on
x86. There are multiple forms of NOP instruction on x86 with different
sizes. Currently, LLVM's assembly/disassembly does not support all forms
correctly which can lead to a breakage of input code semantics, e.g. if
the program relies on NOP instructions for reserving a patch space.
Add "--keep-nops" option to preserve NOP instructions.
