MdeModulePkg/HiiDatabase: Fix incorrect AllocateCopyPool size9m11_23
The immediately preceding call, GetBestLanguage, plus the implementation of
HiiGetString, which is called immediately afterwards, make it clear that
BestLanguage is a null-terminated ASCII string, and not just a five byte,
non-null terminated buffer.
Therefore AsciiStrLen is one byte too short, meaning that whether the space
allocated is really sufficient and whether the resultant string is really
null-terminated becomes implementation-dependent. Rather than switching to
AsciiStrSize, we use an explicitly compile-time string length calculation
(both compile-time and run-time approaches are currently used elsewhere in
the codebase for copying static strings).
