CryptoPkg: Fix BaseCryptLib CrtWrapper strncpy and strcatHEADmaster

Following https://bugzilla.tianocore.org/show_bug.cgi?id=2817 this
bug could also apply to strncpy and strcat.

For strncpy use count+1 if smaller than MAX_STRING_SIZE. This still
restricts the destination size to MAX_STRING_SIZE as before but allows
a strncpy when the source is close after destination without triggering
the InternalSafeStringNoAsciiStrOverlap check in AsciiStrnCpyS.

For strcat use the destination string length + the size of the source
string including the terminator as destination size if smaller than
MAX_STRING_SIZE.

Also move both functions to CrtWrapper.c as they do not return the
correct return value. AsciiStrnCpyS and AsciiStrCatS return
RETURN_VALUE instead of a char * to the destination buffer.
