StdLib: Add multi-byte character support. The normal "narrow" character set is now UTF-8 instead of ASCII.

Add library classes which are required by StdLib, but not commonly defined in Platform DSC files, to StdLib.inc.
Modify MB_LEN_MAX to be 4, the maximum length of UTF-8 characters.
Adjust size of internal buffers to be multiples of MB_LEN_MAX instead of assuming 1-byte characters.
Make the XYoffset object public and move its declaration into EfiSysCall.h.
