Cache Webview::Availability() result for startup checks

Browse Source 
Iv::ShowButton() and LocationPicker::Available() each called
Webview::Availability() separately (~200ms each on Linux). Replace
the per-caller static caches with a single shared cache in
Core::CachedWebviewAvailability(), reducing startup from two
~200ms calls to one.
