MdePkg BaseLib: API PathRemoveLastItem not handle root paths properly
https://bugzilla.tianocore.org/show_bug.cgi?id=239
When the input path for API PathRemoveLastItem() is a root path like
'fs0:\', the API will return TRUE (indicating a directory or file was
removed from the path) and modifies the path to 'fs0:'. In fact, there's
no directory or file removed in the above case.
This commit adds additional check to resolve this issue and modifies the
API's description to make it more straightforward.
