a11y: Change HC icon theme first
There are two ways for applications to provide a high contrast icon:
1. install an icon into the HighContrast theme
2. install a symbolic icon into the default hicolor theme
The latter is preferred nowadays, and implemented in the high-contrast
CSS variant by enforcing the symbolic icon style.
However together with the way we currently enable/disable high-contrast,
this can lead to the following race:
1. the GTK theme is changed from HighContrast
2. we reload the default stylesheet
3. the icon style changes to "regular", so we request a
new icon from the HighContrast icon theme
4. the icon theme is changed from HighContrast
5. we evict existing icons from the cache
6. we reload icons for the new icon theme; however as we
find a pending request (from 3), we re-use it
7. the request from 3 finishes, and we end up with a
wrong icon in the cache
The simplest fix is to change the icon theme before the GTK theme: Unlike the
theme name, the icon style is encoded in the cache key, so we won't re-use
an old (and incorrect) request in that case.

dbusServices: Add some base classes for small stand-alone services
There are a couple of D-Bus services that are currently provided by
gnome-shell for which it makes sense to move them fully or partially
into separate processes:
This caches GAppInfo so that the compositor thread does not have to perform
costly disk access to load them. Instead, they are loaded from a worker
thread and the ShellAppCache notifies of changes.
To simplify maintenance, ShellAppCache manages this directly and the
existing ShellAppSystem wraps the cache. We may want to graft these
together in the future, but now it provides the easiest way to backport
changes to older Shell releases.
Another source of compositor thread disk access was in determining the
name for an application directory. Translations are provided via GKeyFile
installed in "desktop-directories". Each time we would build the name
for a label (or update it) we would have to load all of these files.
Instead, the ShellAppCache caches that information and updates the cache
in bulk when those change. We can reduce this in the future to do less
work, but chances are these will come together anyway so that is probably
worth fixing if we ever come across it.
