Diana Picus abbb0f901a [flang] Change complex type define in runtime for clang-cl
When compiling the runtime with a version of clang-cl newer than 12, we
define CMPLXF as __builtin_complex, which returns a float _Complex type.
This errors out in contexts where the result of CMPLXF is expected to be
a float_Complex_t. This is defined as _Fcomplex whenever _MSC_VER is
defined (and as float _Complex otherwise).

This patch defines float_Complex_t & friends as _Fcomplex only when
we're using "true" MSVC, and not just clang-pretending-to-be-MSVC. This
should only affect clang-cl >= 12.
