gdb: Consolidate 32bit-pkeys.xml and 64bit-pkeys.xml
1. Since 32bit-pkeys.xml and 64bit-pkeys.xml are identical, consolidate
them into a single keys.xml.
2. Enable PKU for x32 to fix:
$ gdbserver :123456 x32-program
...
.../gdbserver/regcache.cc:255: A problem internal to GDBserver has been detected
.
Unknown register pkru requested
on Tiger Lake.
