Bug 1689398 added support for CET User Shadow Stack strict mode, but we have decided that a safer initial approach is to use compatible modules only mode.
This guards against any non-Mozilla DLLs (either loaded by us or injected into the process) causing CET crashes.

We will only run the processes in CET compatible modules only mode when not
using the JIT code. So marking xul.dll as compatible should be OK.
Depends on D117550
