perf arch: Support register names from all archs
When reading a perf.data file with register values, there is a mismatch
between the names and the values of the registers because the tool is
built using only the register names from the local architecture.
Reading a perf.data file that was recorded on ARM64, gives the following
erroneous output on an X86 machine:
# perf report -i perf_arm64.data -D

As can be seen, the register names correspond to X86 registers, even
though the perf.data file was recorded on an ARM64 system. After this
patch, the output of the command displays the correct register names:
# perf report -i perf_arm64.data -D

Athira reports:
"Looks good to me. Tested this patchset in powerpc by capturing regs in
powerpc and doing perf report to read the data from x86."
