This may be useful for tracking TSO faulting when it manages to fetch
stale data. While most TSO crashes are due to nullptr dereferences, this
can still check for the corruption case.
FEXCore doesn't need track the TLS state of the SignalDelegator, this is
a frontend concept.
Removes the tracking from the backend and keeps it in the frontend.
Which requires moving LinuxEmulation to its own independent folder as
well. Since both IRLoader and FEXLoader rely on it.
No functional change, just moves the the code around.
