<i18n dev> RFR: 8370420: HostLocaleProviderAdapter_md.c from libjava can use GetLocaleInfoEx, GetCalendarInfoEx, EnumCalendarInfoExEx directly

[Justin Lu]

This PR cleans up some native code for Windows i18n functions. These particular calls are designed to run on Windows Vista and later. Since Vista (and older) are not supported Windows platforms, the calls no longer need to be checked if they are supported and can be called directly.

Reference to docs: https://learn.microsoft.com/en-us/windows/win32/api/winnls/nf-winnls-getlocaleinfoex.

> Minimum supported client: 	Windows Vista
> Minimum supported server: 	Windows Server 2008
