InvalidationTracker: Fix queries in the non-intersecting RWX case
...
This needs to return the base of the non-RWX interval, with a size
that when added to the base is the start of the RWX interval.

Allocate the stack with uncommited guard pages on either side, if

reset to the default and execution resumed.

LookupCache: Move CodePages to GuestToHostMap
...
Prevents invalidations being missed under the following circumstances:
Thread A JITs block A into the global codebuffer, adding the guest to host
mapping to its CodePages, thread A is then killed.
Thread B then performs SMC on block A. An exception will be triggered but
as CodePages was stored per-thread, and thread A is now killed when all
threads are iterated over by the frontend to perform invalidations it
will be missed.
The accumulator is introduced to handle the case where multiple threads
have the same code entry in their local caches but share the same codebuffer.
Consider a thread C in the above example that also has block A in its cache,
without an accumulator, when invalidating thread B the entrypoint of A is erased
from the shared guest to host map. So when C is invalidated, the local cache entry
for A is not removed since it was removed from CodePages when invalidating B.

Wine: Implements support for profile stats
...
This is a little trickier, we actually open the
`/dev/shm/fex-<pid>-stats` file directly using Windows APIs that way
Mangohud (which is going to be on the Linux side, or potentially even
embedded in to Gamescope) can safely pick up the stats.
A little quirky plus doesn't support expanding its size since WINE
doesn't support NtExtendSection, but that's fine.

HostFeatures: Moves MIDR querying to the frontend

The MIDR querying is inherently OS specific and needs a bit of special
casing. Instead let the frontend inform FEXCore how many CPU cores there
are and their MIDRs instead.
This lets us keep the Linux specific code in the frontend.
