[arm] Add big-endian version of pcrel fixups for adr instructions
Summary:
In 2e24219d3cbf, a number of ARM pcrel fixups were resolved at assembly
time, to solve PR44929. This only covered little-endian ARM however, so
add similar fixups for big-endian ARM. Also extend the test case to
cover big-endian ARM.
