Following up on r1890668, implement ARM64 support in Win32 crash handler.

I'm currently unable to test this, but things look valid, when following
the SDK rules.

* subversion/libsvn_subr/win32_crashrpt.c
  (write_process_info): Dump registers as defined by the SDK.
  (write_stacktrace): Set stack base, based on context. Should work,
    but untested for now.
