  [BOLT][AArch64] Handle .plt.got section (#71216)

It seems that currently this section is only created by the mold linker
if 2 conditions are met: 1. The PLT function was called directly. 2. The
indirect access to PLT function was found (e.g. through ADRP
relocation). Although mold created symbol for every plt entry I've
removed them in yaml file to check that .plt.got was truly disassembled
by bolt.
