MdeModulePkg: Add the EFI_PRINT2S_PROTOCOL 

Add the EFI_PRINT2S_PROTOCOL as a safe version of the EFI_PRINT2_PROTOCOL,
the EFI_PRINT2S_PROTOCOL replaces the following 2 services in
EFI_PRINT2_PROTOCOL:
UNICODE_VALUE_TO_STRING
ASCII_VALUE_TO_STRING

with:
UNICODE_VALUE_TO_STRING_S
ASCII_VALUE_TO_STRING_S

The 2 new services perform checks to the input parameters and will return
relative status to reflect the check result.

Return RETURN_INVALID_PARAMETER when:
1). The input Buffer is NULL.
2). The input BufferSize is greater than (PcdMaximumUnicodeStringLength *
sizeof (CHAR16) + 1) for UnicodeValueToStringS or greater than
PcdMaximumAsciiStringLength for AsciiValueToStringS.
3). The input Flags is not set properly.
4). The input Width is not smaller than MAXIMUM_VALUE_CHARACTERS.

Return RETURN_BUFFER_TOO_SMALL when:
1). The input BufferSize cannot hold the converted value.
