Done by updating the definitions for AX and items to SSize_t
The bootcheck macros will require a bit more work, and need
a separate test.

64-bit stack: XS boot helpers
I'm not entirely happy with this, since we're changing the return
type and the types of the items and ax values passed via va_args.
But an excuse: the return and the fetching of ax and items via
va_args both happen after we've validated the handshake key, which
would prevent the va_arg() fetches and the return.
But but: this is fine for va_args, but purely the call to the
function with the different return type is technically undefined
behaviour.
I'm not sure it's worth trying to workaround that, since it will
require code duplication for a rare case, that I expect to just
work on the platforms involved (64-bit platforms).

64-bit stack: reorganise to allow running single tests
The tests here move/set a lot of memory, and this makes them slow.
If we want to debug a particular test, running them all wastes
a lot of time, so allow particular tests to be run.

64-bit stack: pp_list used I32 to save the mark

This ended up being fixed by one of Dave's rc_stack patches, but leave
the test in.

64-bit stack: eval_sv() mark and argument count handling
eval_sv() had two problems, it saved the starting stack position
in an I32, so a call with a deep stack would save a negative or
otherwise invalid depth, and the return value was an I32, so
if the eval returned a large list the return count would overflow.

64-bit stack: call_sv mark and return value handling
call_sv() used I32 for a saved mark and the return value.
The XS::APItest call_sv() wrapper used an I32 index to reposition
the argument list supplied to call_sv().
I haven't created additional tests for call_argv(), call_pv() nor
call_method(), these simply pass the return value on, I don't think
it worth the extra tests.

Log Message:

Several updates to support an argument stack over 2**31 entries on 64-bit
systems
This makes MARK and most argument stack offsets and item counts into SSize_t
instead
of I32.
You will need at least 32GB of memory just to store the argument stack
itself to reach these limits.
Fixes #20917
