[KERNEL32]: Add/update localized codepage display names.

[KERNEL32]: Add/update localized codepage display names.
- Slightly update the description of CP 28599;
- Add descriptions for CPs 28600, 28603, 28604 and 28606;
- Add CP 856 "OEM - Hebrew PC" (which differs from OEM Hebrew CP 862).
Note that while we also have codepages 424, 878 and 1006, I don't add their description because:
- CP 424 is actually CP 20424 "IBM EBCDIC - Hebrew" on Windows (documented in the resource files);
- CP 878 is actually CP 20866 "Russian - KOI8" on Windows (documented in the resource files);
- CP 1006 seems to be "IBM Arabic" according to Wine, but I don't know its corresponding number on Windows.
