As section permissions are set on the unix side we don't get a
protection callback for them, workaround this by iterating over
the sections of all executables after mapping and tracking the RWX
ones.
Unmapping a section will unmap the whole size initially allocated,
irrespective of how their protections are changed afterwards. Make sure
to follow this logic for invalidation too.
When thread management was moved to the frontend, invalidation moved
from being a global operation to per-thread but the WOW64 backend wasn't
updated to account for this. Now for any invalidation event loop over
all threads tracked by the frontend and invalidate the appropriate
range.
FEXCore includes was including an FHU header which would result in
compilation failure for external projects trying to link to libFEXCore.
Moves it over to fix this, it was the only FHU usage in FEXCore/include
