__MINGW64_TOOLCHAIN__ macro is more readable and shorter than the standard
predefined __MINGW64_VERSION_MAJOR and __MINGW32_TOOLCHAIN__ is defined for
the symmetry and also because it will make many tests simpler as we often
need to test not so much for MinGW-w64 for its own sake but rather to disable
the workarounds for MinGW32 when using it.

During the refactoring of r74496, the logic of the check for Intel compiler
was slightly altered resulting in not defining __VISUALC__ for it any longer
which broke compilation with it.
Restore this definition now to fix it, even though it could admittedly be
better to explicitly check for __INTELC__ in the places where we currently
only check for __VISUALC__ and reserve the latter only for the case when we
are really using MSVC.
Closes#15359.

Do keep compiler-specific wxCHECK_MINGW32_VERSION() in wx/compiler.h as it's
needed by wx/cpp.h which includes wx/compiler.h only. But put the rest of the
stuff in gccpriv.h in its old place as including it before wx/setup.h didn't
work correctly and was unnecessary anyhow.

This solves the problem with wx/defs.h -> wx/platform.h -> wx/setup.h which
resolves to msvc/wx/setup.h -> wx/version.h -> wx/cpp.h include path which
resulted in __VISUALC__ not being defined in wx/cpp.h.
This problem was not new but went unnoticed for a long time and was only
discovered when wxCHECK_VISUALC_VERSION() started being used in wx/cpp.h too
as now the compiler started warning about wrong #if syntax due to it being
undefined.
Putting the compiler-specific definitions in a separate file allows this file
to be included from wx/cpp.h to ensure that these symbols are always defined
in it and also makes things a little better organized.
