windows: prefer 64-bit time_t (#25666)

Browse Source 
time_t should be a 64-bit type on all relevant windows CRT versions
including mingw-w64 - MSDN recommends against using the 32-bit version
which only is happens when `_USE_32BIT_TIME_T` is explicitly defined -
instead of guessing (and guessing wrong, as happens with recent mingw
versions), we can simply use the 64-bit version always.

(cherry picked from commit e53058dee0)
