Patch that adds a single-entry sortguid cache to sortkey_compare

Wine-Staging patchset libs-Unicode_Collation makes CompareStringEx far slower
than before. This is because the sortkey_compare function added by the last
patch and used by CompareStringEx makes a call to get_language_sort, which is
not exactly cheap (it reads from the registry which involves server calls).

A small patch that adds a simple cache for the last used sortguid makes the
search function fast again.
