Uses dynamicLightColorScheme and dynamicDarkColorScheme based on the
app's theme to style the header. This allows the App Header to use
light/dark variants of color tokens even if the app theme and system
theme are not aligned, whereas before, "inverse" tokens (resolved with
the system context) had to be used for apps not following the system
theme, which are much more limited than non-inverse tokens.

Bug: 328668781
Test: App Header of light app on dark system theme and viceversa
always follows the app theme and focus / unfocused headers are
differentiated

This is so that different Enter/Exit logging reasons can be differentiated by the DestopModeLoggerTransitionObserver.

Create a TransitionSource enum which is shared with Launcher. Methods read TransitionSource passed to them and decide on which transitionType to choose when starting transitions.

**CUJ -> TransitionType -> Enter/ExitReason**

**Earlier**
Enter: Handle button -> MOVE_TO_DESKTOP -> APP_HANDLE_MENU_BUTTON
Enter: App icon(overview) -> MOVE_TO_DESKTOP -> APP_HANDLE_MENU_BUTTON
Enter: Keyboard shortcut -> MOVE_TO_DESKTOP -> APP_HANDLE_MENU_BUTTON
Exit: Drag to exit -> EXIT -> DRAG_TO_EXIT
Exit: Handle button -> EXIT -> DRAG_TO_EXIT
Exit: Keyboard shortcut -> EXIT -> DRAG_TO_EXIT

**Now**
Enter: Handle button -> APP_HANDLE_MENU_BUTTON -> APP_HANDLE_MENU_BUTTON
Enter: App icon(overview) ->APP_ICON_FROM_OVERVIEW->UNKOWN (fix later)
Enter: Keyboard shortcut -> KEYBOARD_SHORTCUT -> KEYBOARD_SHORTCUT
Enter: Adb Commands -> ADB_COMMANDS -> UNKNOWN (debugging CUJ only)
Exit: Drag to exit -> EXIT -> DRAG_TO_EXIT
Exit: Handle button -> APP_HANDLE_MENU_BUTTON-> APP_HANDLE_MENU_BUTTON

Changing the process of how the IME is shown or hidden:
- Showing or hiding the IME is driven through its requested visibility (InsetsControlTarget) via InsetsController/DisplayImeController and thus sent to the server (InsetsStateController).
- When hiding the IME, the requestedVisibleTypes are sent after the end of the animation.
- Introduced new OnImeRequestedChangedListener that is called via WindowManagerService that is called to start the show/hide IME flow in IMMS.
- When the IME becomes (un)available, its leash is (re)set.
- Show/Hide requests from InputMethodManager are redirected through InsetsController.

Currently, when we exit the maximize menu quickly when hovering, we
sometimes do not receive the ACTION_HOVER_EXIT call when the following
occurs:
1. User hovers over the maximize menu and we receive an
   ACTION_HOVER_ENTER.
2. User quickly exits the menu by hovering downwards and hovers over one
   of the maximize menu's buttons. We recieve a ACTION_HOVER_ENTER and
   then a ACTION_HOVER_EXIT from the view.
3. Given the small margin below the button and the speed at which the
   hover occurs, the maximize menu view does not register the hover so
   we never receive the ACTION_HOVER_EXIT. Therefore, the close menu
   runnable is never posted.

To fix this issue, this change has the listener post the close menu
runnable whenever any menu view is exited and removes the callback if
there is an ACTION_HOVER_MOVE over any view to assure that we do not
prematurely close the menu when we exit a button in the menu without
fully exiting the menu.

Bug: 327677202
Test: Open the menu by hovering over the maximize button and quickly
exit.

The screenshot for animation needs to be "setAllowProtected(true)",
otherwise the protected area will be blank. But it is unable to
be used to extract color because protected content is not readable.

To avoid the background rotation animation always showing black
color in this case (it looks flickering if the main color of screen
is light), use the source surface with excluding protected content
to calculate the color.

* Previously gesture was disabled when we started both apps
from launcher (overview, workspace, all apps etc)
* This handles the case when we start split from in-app taskbar,
in that case the transitions finishes much faster and launcher was
getting the disable flag turned off before the side animation finished.
* Now for enter transitions that are resizing, we delay turning the
disable flag off until after the animation completes
* Button nav version of this still needs to be handled (separate path
