Remove obsolete wxCHECK_W32API_VERSION() checks

The latest of those checks tested for w32 API 3.3, which is older than
MinGW 3.4 released which is more than 13 years old, so we can safely
drop them (let alone checks for prehistoric 0.5 w32 API).

This incidentally fixes compilation errors due to the use of
wxCHECK_W32API_VERSION() in wx/msw/winundef.h which was now (since
the changes of 8c572c0a77) included before
this macro was defined.
