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.
