[ASan] Mark recent integration tests as accordingly for MSVC

[39otsu]

Both of these tests will cause an unsuccessful pass when using msvc.

shadowed-stack-serialization.cpp - XFAIL due to the metadata not being generated.
fakeframe-right-redzone.cpp - UNSUPPORTED due to the optimization limitations of the msvc compiler.

nit: here msvc is capitalized (i.e. "MSVC") but in your other file it's not (i.e. "msvc").
It seems the codebase mostly uses the latter form. I recommend using the latter form in both files
