Unfortunately we can't keep it in wx/compiler.h which is included too early,
before UNICODE macro is defined, and we can't define it before including
wx/setup.h which itself must be included after wx/compiler.h.
So move it to wx/msw/gccpriv.h which is not a great solution, as the best
would be to get rid of this gcc-specific file completely, but at least should
make everything build again and ensure that _mingw.h is included after UNICODE
definition.
Closes#15805.

This undoes r74888, r74913 and r74969 because all of them were still not
enough to make ICC build work correctly. So instead of trying to find all the
places where we need to test for __INTELC__ in addition to __VISUALC__, just
revert to defining __VISUALC__ for ICC under Windows as it uses its CRT anyhow
and in the vast majority of cases we are actually testing for the CRT and not
the compiler anyhow.

This is confusing and makes it more difficult to test for the "real" MSVC,
test for __INTELC__ explicitly wherever needed instead.
Also document __INTELC__ in our list of compilers.

__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.

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.
