Add Universal Windows Platform support

[isaevil]

Support compilation with Universal Windows Platform by fixing compilation errors like these:

doctest.h(4272): error C3861: 'SetThreadStackGuarantee': identifier not found
doctest.h(4305): error C2065: 'SEM_FAILCRITICALERRORS': undeclared identifier
doctest.h(4305): error C2065: 'SEM_NOALIGNMENTFAULTEXCEPT': undeclared identifier
doctest.h(4306): error C2065: 'SEM_NOGPFAULTERRORBOX': undeclared identifier
doctest.h(4306): error C2065: 'SEM_NOOPENFILEERRORBOX': undeclared identifier
doctest.h(4324): error C3861: 'SetThreadStackGuarantee': identifier not found

I think a cleaner way to do this would be to add the follownig:

#ifdef WINAPI_FAMILY
#define DOCTEST_CONFIG_NO_WINDOWS_SEH
#endif // WINAPI_FAMILY

in doctest_fwd.h - right around line 230 before #if DOCTEST_MSVC && !defined(DOCTEST_CONFIG_WINDOWS_SEH) - along with a comment.

I'm not familiar at all with WINAPI_FAMILY and the relations with WINAPI_FAMILY_APP & WINAPI_FAMILY_PHONE_APP & WINAPI_PARTITION_DESKTOP, but there are such checks already in doctest.cpp (#if defined(WINAPI_FAMILY) && (WINAPI_FAMILY == WINAPI_FAMILY_APP)) which are specific - much better than something as broad as WINAPI_FAMILY.

And btw thanks for the contributions - even though I request changes in each and every single of your PRs - more compiler/platform support is welcome!

I guess this check you mentioned #if defined(WINAPI_FAMILY) && (WINAPI_FAMILY == WINAPI_FAMILY_APP) is actually applicable here too because as I can see we define /DWINAPI_FAMILY=WINAPI_FAMILY_APP in our project.
