Doesn't change the default behavior, but allows plugins to add their
view behind the main view, which gives more control over what happens
with inputs and can be useful along with transparent rendering.
This is done by providing API access to app specific directories which don't have any limitations and allows us to bump the target sdk version to 30.
In addition, we're also bumping the min sdk version to 19 as version 18 is no longer supported by Google Play Services and only account of 0.3% of Android devices.
This makes for easier organization since downloading a project
several times (or several different projects) will result in more
meaningful file names.
This prevents the D-pad up arrow from being registered as pressed
when it isn't, and pressing any direction from activating the next
arrow clockwise of it.

Key, touch and joystick events will be passed directly from the UI thread to Godot, so they can benefit from agile input flushing.
As another consequence of this new way of passing events, less Java object are created at runtime (`Runnable`), which is good since the garbage collector needs to run less.
`AndroidInputHandler` is introduced to have a smaller cross-thread surface. `main_loop_request_go_back()` is removed in favor just inline calling `send_window_event()` at the most caller's convenience (i.e., leveraging the new `p_deferred`` parameter as appropriate).
Lastly, `get_mouse_position()` and `get_mouse_button_state()` now just call through `Input` to avoid the need of sync of mouse data tracked on the UI thread.
Input buffering is implicitly used by event accumulation, but this commit makes it more generic so it can be enabled for other uses.
For desktop OSs it's currently not feasible given main and UI threads are the same).
- API has been simplified: all events now go through `parse_input_event()`. Whether they are accumulated or not depends on the `use_accumulated_input` flag.
- Event accumulation is now thread-safe (it was not needed so far, but it prepares the ground for the following changes).
- Touch drag events now support accumulation.
This was caused by the fact that a new instance of Godot was created at resume while a previous instance already existed.
The previous instance would then go through its cleanup lifecycle, and would thus attempt to close the entire app, leading to the system to restart the app, thus starting the cycle anew.
The fix involves reusing the previous instance of Godot if one is available instead of creating a new one, as well as giving control to the host activity for how the process should be terminated.
