[Patch, Arm, Readelf] Support for a new pacbti unwind opcode.

[Tejas Belagod]

Hi,

This patch adds readelf support for decoding the exception table opcode for restoring the RA_AUTH_CODE pseudo register defined by the EHABI (https://github.com/ARM-software/abi-aa/releases/download/2021Q1/ehabi32.pdf Section 10.3).

Tested for arm-none-eabi. OK for master?

Thanks,
Tejas.
