MdePkg: Enhance PathRemoveLastItem() to support "FS0:File.txt"
The original implementation only looks for very last backslash
and removes the string after that.
But when the path is like "FS0:File.txt" which doesn't contain
backslash, the function cannot work well.
The patch enhances the code to look for very last backslash or
colon to support the path which doesn't contain backslash.
