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".

Very thoroughly checked signal connections and deferred calls to this method, add_do_method/add_undo_method calls, and so on. Also renames the internal `_update_callback()` to `_redraw_callback()` for consistency. Just a few comments have also been changed to say "redraw".

Move ParticlesMaterial code to its own resource file It's shared by both 2D and 3D particles (+ CPU ones), so it makes sense to have as a common resource. It also allowed to disable compilation of Particles (3D) when using 'disable_3d'. Also cleaned up includes in SpatialEditorGizmos and some other places, as well as dropped dead code in material_editor_plugin.cpp.

Variant: Added 64-bit packed arrays, renamed Variant::REAL to FLOAT. - Renames PackedIntArray to PackedInt32Array. - Renames PackedFloatArray to PackedFloat32Array. - Adds PackedInt64Array and PackedFloat64Array. - Renames Variant::REAL to Variant::FLOAT for consistency. Packed arrays are for storing large amount of data and creating stuff like meshes, buffers. textures, etc. Forcing them to be 64 is a huge waste of memory. That said, many users requested the ability to have 64 bits packed arrays for their games, so this is just an optional added type. For Variant, the float datatype is always 64 bits, and exposed as `float`. We still have `real_t` which is the datatype that can change from 32 to 64 bits depending on a compile flag (not entirely working right now, but that's the idea). It affects math related datatypes and code only. Neither Variant nor PackedArray make use of real_t, which is only intended for math precision, so the term is removed from there to keep only float.

Fixes missng 2D engine bits -Mesh2D now works -MultiMesh2D now works -Polygon2D now works -Added hooks for processing 2D particles -Skeleton2D now works 2D particles still not working, but stuff needed for it is now implemented.

Use global coordinates for particles by default Particles won't move or rotate anymore with the node (or its parents) by default. This new default behavior is generally more suited to most use cases. Local coordinates can still be enabled on a per-node basis. This affects both 2D and 3D particles, and both CPU and GPU-based particles.
