Update desktop mode caption bar to newest spec
Updates the caption bar layout in proto1/proto2 to a new model with a
close button and an app info view group. Also applies a small
refactor so that ALL views are updated only from relayout using the
latest task state instead of allowing certain views to be updated
independently (such as caption/color from onTaskInfoChange or button
clicks), which led to some synchronization issues leading to visual
errors.
Visual changes:
1. In proto 1 / proto 2 (desktop mode), the caption now has a close
button and the handle bar was replaced with a left-aligned view group
which contains the app icon, app name and an expand button which when
clicked opens the handle menu. The middle section of the caption bar
(between the app info and the close button) is now what allows
dragging and moving the task.
2. In proto2, the handle menu is aligned to the left when in
desktop mode. It continues to be centered when in fullscreen
3. Fixes issue where the app handle was sometimes invisible in proto2
on fullscreen tasks.
4. In proto1, the caption handle color was (sometimes) set based on
whether desktop mode was active (to dark or light). This conflicted
with other logic that sets it based on luminocity of the status bar
color to provide contrast. This CL removes the logic based on desktop
mode status since it didn't really make sense considering the whole
caption is invisible when desktop mode is inactive.
5. In proto1, the caption visibility was set based on the task focus
state. It is now always visible to match proto2 (desktop) behavior.
Non-visual changes:
1. Split the window decoration layout into two xml files (one for
each possible 'type' of caption): FOCUSED (used by proto1 and proto 2
when in fullscreen mode) and APP_CONTROLS (used by proto2 when in
desktop). This simplifies the visibility/color updates
that #relayout deals with. Instead of a single layout containing all
possible views of the caption and having to hide and show some
depending on which caption type was "active" at the time, the split
layouts now contain only the views that are relevant to that type,
so #relayout can check the type of caption and apply updates to only
the views that are actually affected by the current state.

Test: Enter desktop mode in proto2 and see new spec; Switch between
modes in proto1 and make sure the new spec is visible in desktop
mode only.
