    [PSEH] Fix SEH compatibility macros for dummy PSEH
    This is used with Clang, which does have native SEH, but it's broken and can cause
the compiler to crash. Previously some code was not handling this and instead used native
SEH for clang. Fix this by always using _SEH2_* macros instead of relying on __USE_PSEH2__
to be defined.
