The `__SEH__` built-in define is only defined in mingw mode; in MSVC mode it's implied.

This makes a libunwind built with clang-cl in MSVC mode actually do unwinding using the SEH information instead of DWARF.

After D86041 <https://reviews.llvm.org/D86041>, this should make the now successfully built libunwind actually do the right thing as well.
