Replace multiple, consecutive "\" characters prior to other processing
involving "\" characters. This fixes an issue where "\\..\\..",
"//..//..", and similar input paths are not cleaned properly.

MdePkg-BaseLib: Fix PathCleanUpDirectories() error involving "\..\.."
The loop that removes "xxxx\..\" errs when multiple "\.." sequences are
in the path. Before this change the code would modify a path like
"FS0:\efi\tools\..\.." to "FS0:\efi\\.." and then to "FS0:\efi\", but
the correct path is "FS0:\".
You can test the effect of this change in the shell by setting the
current directory to something like FS0:\efi\boot and then executing
the command "ls ..\..". Before the change you will see the files in
the FS0:\efi directory; after the change, you will see the files in
the root directory of FS0:.

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=705
As mentioned in the above Bugzilla link by Steven, within the function
PathCleanUpDirectories(), when executing command:
"cd ."
under Shell, the input parameter 'Path' string will have string length
less than 2. Hence, it is possible for the below statement:
"if (StrCmp (Path + StrLen (Path) - 2, L"\\.") == 0) {"
to read contents before the string boundary.
This commit adds additional checks to avoid this.

The old code incorrectly cleans path like "fs0:\abc\.\.." to
"fs0:\abc", instead of "fs0:\"

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.

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.
