devel/gdb: Update to 12.1.

One notable feature included in 12.1 is async target support
permitting the use of commands like continue&.

In addition, this commit backports various post-12 commits to add
support for hardware breakpoints/watchpoints on aarch64, support for
resolving TLS variables from core dumps on amd64 and i386 via the
recently added NT_X86_SEGBASES core dump note, and support for
resolving TLS variables on arm and aarch64 via the recently added
NT_ARM_TLS register set.

devel/gdb: Fix kernel backend registrations.

Per-architecture kernel backends are registered via GDB initialization
routines.  The GDB build uses a regular expression to identify the
initialization routines invoked during startup.  This regular
expression requires a single space between the function name and it's
empty argument list.  However, the initializers for aarch64, arm,
mips, and riscv had two spaces before the empty argument list causing
those backends to not be registered and the corresponding architecture
kernels to not be recognized.  Fix by removing the spurious spaces.

Fix a couple of issues in kgdb.

- Properly unwind across in-kernel exceptions on arm.

- Enumerate processes via the pid hash table for kernels without the
  zombproc list.

Fixes for kgdb including initial FreeBSD/arm support.

- Improve fallback handling for the read of pcb_size.

  If for some reason kgdb has only the kernel's debug info, a read of
  pcb_size will simply return 0, resulting in an exception when unwinding
  the stack of a thread that was on a CPU at the time the dump was
  created.  In this case, fall back to using sizeof(struct pcb).
- Always supply a value for the PC register on x86.

  A thread's PCB may have been swapped out, and a dummy value ensures that
  we don't get an exception while enumerating threads in a dump.
- Mark all 64-bit address bits as valid for aarch64 kernels.

  ARMv8 supports pointer tagging in which case the upper 8 bits of VAs are
