One Copyright Update to rule them all As many open source projects have started doing it, we're removing the current year from the copyright notice, so that we don't need to bump it every year. It seems like only the first year of publication is technically relevant for copyright notices, and even that seems to be something that many companies stopped listing altogether (in a version controlled codebase, the commits are a much better source of date of publication than a hardcoded copyright statement). We also now list Godot Engine contributors first as we're collectively the current maintainers of the project, and we clarify that the "exclusive" copyright of the co-founders covers the timespan before opensourcing (their further contributions are included as part of Godot Engine contributors). Also fixed "cf." Frenchism - it's meant as "refer to / see".

Switch to input buffering on Android 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.

// This class encapsulates all the handling of input events that come from the Android UI thread.

// - It's not thread-safe by itself, so its functions must only be called on a single thread, which is the Android UI thread.

Input logic cleanup: - Fix invalid detection of mouse input. Prioritize using the event tool type to detect the type of the event, and only use the event source as fallback. - Ensure that pressure and tilt information is passed for touch drag events - Consolidate logic and remove redundant methods - Improve the logic to detect when external hardware keyboards are connected to the device

Use BitField<> in core type masks * All core types masks are now correctly marked as bitfields. * The enum hacks in MouseButtonMask and many other types are gone. This ensures that binders to other languages non C++ can actually implement type safe bitmasks. * Most bitmask operations replaced by functions in BitField<> * Key is still a problem because its enum and mask at the same time. While it kind of works in C++, this most likely can't be implemented safely in other languages and will have to be changed at some point. Mostly left as-is. * Documentation and API dump updated to reflect bitfields in core types.

Augment the `InputEvent` class with a `CANCELED` state The `InputEvent` class currently supports the `pressed` and `released` states, which given the binary nature, is represented by a `bool` field. This commit introduced the `CANCELED` state, which signals that an ongoing input event has been canceled. To represent all the states, the `InputEventState` enum is added and the `InputEvent` logic is refactored accordingly.
