[jdk17u-dev] RFR: 8272352: Java launcher can not parse Chinese character when system locale is set to UTF-8 [v2]

[Stephanie Crater]

> Backport to allow java to correctly parse Chinese characters in file paths and string arguments passed to java.exe.
> 
> Java runtime has been detecting the Windows system locale encoding using `GetLocaleInfo(GetSystemDefaultLCID(), LOCALE_IDEFAULTANSICODEPAGE, ...)`, but it returns the _legacy_ ANSI code page value, e.g, 1252 for US-English. In order to detect whether the user has selected `UTF-8` as the default, the code page has to be queried with `GetACP()`.
> Also, the case if the call to `GetLocaleInfo` fails changed to fall back to `UTF-8` instead of `Cp1252`.
