This is a much simpler attempt to solve the same problem as #76060, but
without breaking any compatibility.
* Adds a description of what model space is in the Vector3 enums
(MODEL_* constants). This has the proper axes laid out for imported 3D
assets.
* Adds the option to `look_at` using model_space, which uses
Vector3.MODEL_FRONT as forward vector.
The attempt of this PR is to still break the assumption that there is a
single direction of forward (which is not the case in Godot)
and make it easier to understand where 3D models are facing, as well as
orienting them via look_at.

Also bound the new Basis helper methods.
- Implement shadow fading when using the Orthogonal shadow mode
(like in `master`).
This allows customizing the distance at which directional shadows
start to fade away. Shadow fading will also always start at the same
distance now, regardless of the current shadow mode in use.
This is useful for enclosed levels to prevent shadows from fading
at all with a well-tuned maximum distance.
The default fade start value (0.8) results in fading happening later
in the distance compared to the previous behavior, where fading started
from the last shadow split distance (0.6 in PSSM 4 Splits and
0.1 in PSSM 2 Splits).
* Move client interpolation pump to earlier in the iteration before 3D physics synced
* Allow `get_global_transform_interpolated()` to prime the client interpolation inside a physics tick
* Moves 3D Camera interpolation scene side.
* Automatically switches `get_camera_transform()` to report interpolated transform during `_process()`.
* Fixes `ClippedCamera` to work with physics interpolation.
Add scene side discrete level of detail.
New node `LOD` for UI, and `LODManager` within `World` for automatically updating child visibilities based on distance from cameras.
