Adjust the behavior of the MdePkg Print Library class to produce a consistent style of EOL characters.
Previously, the Print Library class would translate '\n' to '\n\r'.
With this update, the following EOL translations are performed:
1) '\r' to '\r'
2) '\r\n' to '\r\n'
3) '\n' to '\r\n'
4) '\n\r' to '\r\n'
