Themes: Build icon cache when applying icons

The theme service will schedule building of the icon cache when
an icon pack is applied.  This will allow the icon cache to be
populated immediately after icons are applied rather than build
it up as icons are requested.

Themes: Pass resource IDs instead of bitmaps [1/2]

Rather than passing around bitmaps in the ComposedIconInfo we
can pass the resource IDs associated with each of the components
and retrieve those drawables when composing the icon.

SettingsProvider: add default overlay entry for SEND_ACTION_APP_ERROR

Add a default entry for Settings.Global.SEND_ACTION_APP_ERROR so that it
can be overlayed elsewhere if needed.

Themes: Allow clearing the wallpaper and ls wallpaper

By providing an empty string for the MODS_LAUNCHER and
MODS_LOCKSCREEN components, the theme service will clear out any
existing wallpaper the user had set.  This provides the same
functionality as if the user was picking "No wallpaper" from the
picker.

Fix camera usage tracking.

When a Camera object is finalized, it notifies the torch service that
it's no longer using the camera. This call used to not check whether the
caller actually is still using the camera and called release() before,
so depending on timing of the finalizer, it could happen that e.g. the
camera app released the camera user record of the torch app, leading to
the torch usage not being detected on next usage of the camera app.

Fix that by checking whether the caller of onCameraClosed() actually
owned the camera prior to releasing the record.
Also fix synchronization between accesses.
