Add UnicodeStrToAsciiStrS() and AsciiStrToUnicodeStrS() API.
These 2 safe version APIs are used to replace UnicodeStrToAsciiStr() and
AsciiStrToUnicodeStr() API.
The safe version string convert APIs use similar check as StrCpyS().

Add more comments:
1) EDKII version safe string function is similar as the one C11.
2) If error is returned, the Destination is unmodified.

The StrnLenS and AsciiStrnLenS functions, when presented with a string
with no terminating NULL in the first MaxSize characters will check
the character at String[MaxSize] before checking if Length < MaxSize.
(They return the correct value, but have accessed beyond the stated
limit in the process.)
Flip the order of the tests to prevent this behaviour.
