MdePkg/BaseLib: Introduce CharToUpper and AsciiCharToUpper publicly

Browse Source 
Introduce two public functions CharToUpper and AsciiCharToUpper.
They have the same functions as InternalCharToUpper and
InternalBaseLibAsciiToUpper.Considering the internal functions will
be removed,so directly I change their function names to the public ones'.
