Subject: [PATCH v2 13/31] perf dwarf-regs: Remove PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET

PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET was used for BPF prologue
support which was removed in Commit 3d6dfae88917 ("perf parse-events:
Remove BPF event support"). The code is no longer used so remove.

Remove the offset from various dwarf-regs.c tables and the dependence
on ptrace.h. Rename structs starting pt_ as the ptrace derived offset is
now removed.

Signed-off-by: Ian Rogers <irogers@...gle.com>
