Vadim Zeitlin 70232f52e9 Do define __VISUALC__ when using Intel compiler under Windows.
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.

Closes #15359.

MinGW-w64 project provides compilers for both Win32 and Win64 but only
defines the same __MINGW32__ symbol for the former as MinGW32 toolchain
which is quite different (notably doesn't provide many SDK headers that
MinGW-w64 does include). So we define a separate symbol which, unlike the
predefined __MINGW64__, can be used to detect this toolchain in both 32 and
64 bit builds.
And define __MINGW32_TOOLCHAIN__ for consistency and also because it's
convenient as we often want to have some workarounds only for the (old)
MinGW32 but not (newer) MinGW-w64, which still predefines __MINGW32__.
