Do a JIT rolling build if the JIT-EE GUID changes (#46963)

Normally, any JIT-EE GUID change would be accompanied by
a change in the JIT source code, so a JIT build would be
kicked off. But in some cases, such as a change in the
SuperPMI data format to cause an incompatible format, with
a manual change of the GUID to compensate, should also
kick off a JIT build so asmdiff baselines have a JIT
with an appropriate GUID.
