Hao Wu 0dab57708d MdePkg/BaseLib: AsciiStrToUnicodeStr(S) not handle EASCII properly
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1262

Current implementation of BaseLib APIs:

AsciiStrToUnicodeStr()
AsciiStrToUnicodeStrS()
AsciiStrnToUnicodeStrS()

do not handle EASCII properly.

More specifically, if the value of ASCII character is larger than 0x7F,
then the converted Unicode character will have all '1's in the higher 8
bits.

An example:
  0xC9 => 0xFFC9 (current implementations)
and it should be:
  0xC9 => 0x00C9

This commit will address this issue.
