Leo Yan 5000e7f61a perf parse-regs: Refactor arch register parsing functions 
Every architecture has a specific register parsing function for
returning register name based on register index, to support cross
analysis (e.g. we use perf x86 binary to parse Arm64's perf data), we
build all these register parsing functions into the tool, this is why
we place all related functions into util/perf_regs.c.

Unfortunately, since util/perf_regs.c needs to include every arch's
perf_regs.h, this easily introduces duplicated definitions coming from
multiple headers, finally it's fragile for building and difficult for
maintenance.

We cannot simply move these register parsing functions into the
corresponding 'arch' folder, the folder is only conditionally built
based on the target architecture.

Therefore, this commit creates a new folder util/perf-regs-arch/ and
uses a dedicated source file to keep every architecture's register
parsing function to avoid definition conflicts.

This is only a refactoring, no functionality change is expected.

Committer notes:

Had to add util/perf-regs-arch/*.c to tools/perf/util/python-ext-sources
to keep 'perf test python' passing.
