  [JSC] Harden CustomGetterSetter by adding MethodTable overrides that always 
crash
https://bugs.webkit.org/show_bug.cgi?id=268897
<rdar://122171568>

Reviewed by Mark Lam.

Just like GetterSetter, CustomGetterSetter is never purposely exposed to 
userland code.
However, to make exploitation of accidentally exposed CustomGetterSetter 
objects difficult, this
patch implements MethodTable overrides that abort the program when reached, 
similar to GetterSetter.

This is short-term suggested fix to add isValid check to 
MediaTrackConstraintSetMap to ensure each incomming contraint from IPC call has 
the right MediaConstraintType.
