evil: Implement evil_localtime_r using localtime 

Implements `evil_localtime_r` using win32 [localtime
function](https://docs.microsoft.com/pt-br/cpp/c-runtime-library/reference/localtime-localtime32-localtime64?view=vs-2019).
If `HAVE_lOCALTIME_R` is not defined, define `localtime_r`
as `evil_localtime_r`
