The file just provides the function get_arch_regstr, however, if in
the only caller get_dwarf_regstr EM_HOST is used for the EM_NONE case
the function can never be called. So remove as dead code. Tidy up the
EM_NONE cases for arm64 in dwarf-regs.c.

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.

Check that it is not needed and remove, fixing up some fallout for
places where it was only serving to get something else.

Not needed in this header, added to the places that need FILE,

Removing it from util.h, part of an effort to disentangle the includes
hell, that makes changes to util.h or something included by it to cause
a complete rebuild of the tools.

Both do the same thing, the later is the one we get from
linux/stringify.h, i.e. we now use the same function name/practice as
the kernel sources.

Since HAVE_KPROBES can be enabled in arm64, this patch introduces
regs_query_register_offset() to convert register name to offset for
arm64, so the BPF prologue feature is ready to use.

This patch hooks in the perf_regs and libunwind code for ARM64.
The tools/perf/arch/arm64 is created; it contains the arch specific
code for DWARF unwinding.
