headers: Add support for -D_TIME_BITS=64
Currently all 32-bit non-UCRT builds are forced to use time_t type as
32-bit and also all time_t functions in 32-bit form.
With this change, any msvcrt.dll based 32-bit application can use 64-bit
time_t functions by defining -D_TIME_BITS=64 flag during compilation.
Flag -D_TIME_BITS=64 is recognized also by GNU C library header files for
the same purpose.
When both _USE_32BIT_TIME_T and _TIME_BITS are defined by application then
_USE_32BIT_TIME_T override effect of _TIME_BITS.
