More accurate unsafe motion calculation
* Safe and unsafe motion are calculated by dichotomy with a limited
number of steps. It's good for performance, but on long motions that
either collide near the beginning or near the end, the result can be
very imprecise.
* Now a factor 0.25 or 0.75 is used to converge faster when this case
happens, which allows longer motions to get more accurate collision
detection.
* Makes snap collision more precise, and helps with cases where diagonal collision on the border of a platform can lead to the character being stuck.
Additional improvements to move_and_slide:
* Handle slide canceling in move_and_collide with 0 velocity instead of
not applying it.
* Better handling of snap with custom logic to cancel sliding.
* Remove small jittering when using stop on slope, by canceling the
motion completely when the resulting motion is less than margin instead
of always projecting to the up direction (in both body motion and snap).

* Lua table syntax uses named indexing: `{ mykey = myvalue }`
* Python style syntax uses string indexing: `{ "mykey" : myvalue }`
* Both are incompatible since a StringName key wont fetch a String key, hence confusing.
* This PR proposes always using String for indexing at a very minimal performance cost. Always indexing with StringNames will be faster, but they are considerably more expensive to create.
This is already allowed when using cinematic preview, but not
when previewing a Camera3D the usual way.
Many operations from the View menu still work while previewing
a camera, such as switching between debug draw modes and toggling
information panes.
Vector handles this silently by returning -1, and we should do the same here.
Otherwise we get errors when calling `find()` on e.g. a LocalVector of size 0,
while `find()` is expected to always work (if the parameters are invalid then
it doesn't find anything, so -1).
Fixup to #49925.
It can be turned off in the export preset with `package/classify_as_game`.

Also fixes replacing `android:allowBackup` in custom builds.
* Colors were imported as 16BPP (half float)
* Far most common use cases only require 8BPP
* If you need higher data precision, use a custom array, which are supported now.
**WARNING**: 3D Scenes imported in 4.0 no longer compatible with this new format. You need to re-import them (erase them from .godot/import)
- Locking nodes can now be done by pressing Ctrl + L, and unlocking with
Ctrl + Shift + L.
- Grouping nodes is now done by pressing Ctrl + G, and ungrouping with
Ctrl + Shift + G (similar to Inkscape).
- Toggling the grid is now done by pressing the `#` key
(also similar to Inkscape). This change was needed as Ctrl + G
now groups selected nodes.
Different shortcuts are used for the lock/unlock and group/ungroup
actions, so that the shortcuts are idempotent.
* Removed entirely from RenderingServer.
* Replaced by ImmediateMesh resource.
* ImmediateMesh replaces ImmediateGeometry, but could use more optimization in the future.
* Sprite3D and AnimatedSprite3D work again, ported from Godot 3.x (though a lot of work was needed to adapt them to Godot 4).
* RootMotionView works again.
* Polygon3D editor works again.
New property disable_mode to set different behaviors:
Remove: remove from physics simulation
MakeStatic: change body mode to static (doesn't affect area and soft body)
KeepActive: do nothing
Extra change:
Handle disable/enable node state with specific notifications, in order
to differentiate global pause from disabled nodes.
