Bug 1716462 - Minor WidgetStyleCache cleanup. r=stransky

Browse Source 
We always support these functions, so no need to use dlsym. The csd type
technically depends on the theme I think, so caching it globally is
wrong. Instead compute it once and pass it down to the two callers that
care about it.
