Linux: Converts passthrough syscalls to direct passthrough handlers 
Reimagining of #3355 without any json generators or new concepts.

Fixes some mislabeling of system calls. Some getting inlined when they
shouldn't be, a lot not getting inlined when they can be.

This really cleans up the syscall implementation, all syscalls that can
be passthrough implementations require a very small two line
declaration.
Additionally cleans up a bit of implementation cruft where some
passthrough syscalls were using the glibc syscall handler, and some were
using the glibc implementation. We have had multiple issues in the past
where the glibc implementation does something subtly different than the
raw syscall and breaks things. Now all passthrough handlers do a system
call directly, removing at least one indirection and some ambiguity.

This makes it significantly easier to add new passthrough syscalls as
well. Only need to do a version check and add the three lines per
syscall. Which there are new syscalls incoming that we will want to add.

Tangible improvements:
- Syscalls are lower overhead than ever.
- When I'm adding more syscalls I have less chance of mucking it up.

Linux: Move unimplement ustat and sysfs 
AArch64 doesn't implement these and will return ENOSYS.
Moving them to NotImplemented so we can get a log if an application
tries to use these.

InstcountCI: Add a monster of a game block 
Doing very little work with a bunch of instructions.
Hottest block in the Windows version of Psychonauts, it's just doing a
matrix swizzle but in the worst possible way.

Adds a unittest for a bug from #3421 
When the source arguments for LoadMem/StoreMem have bit 31 set then they
are incorrectly sign extending in some instances.

Detected this when testing #3421 but I don't have a proper fix for it.

6994fc3a01 IR,OpcodeDispatcher,JIT: fuse adcs flags 
The usual tricks, also requires introducing a bare adc op to optimize adcs to,
but we wanted that anyway!

Also support a zero source, so we can calculate "foo + CF" in one instruction to
optimize the "lock adc" cases.
