A new `Math::division_round_up()` function was added, allowing for easy
and correct computation of integer divisions when the result needs to
be rounded up.
Fixes#80358.

Previously, the wrong node id (root node id) was used. Dirty leaf nodes
do not actually recalculate aabb.
Additionally, when requesting a new leaf, mark `dirty` as `false` in `clear()`.
Make sure to only mark the leaf as **dirty** when shrinking the border of
the leaf when removing items.
In other cases, the leaf node's aabb will get the correct result immediately.
1. When adding an item, the leaf nodes will be calculated immediately.
2. Removing the item within the border of the leaf node has no effect on the
original aabb.
Removes a line from Projection::get_z_far that flips the normal of a plane.
While this may be required for similar code elsewhere in the file, this is
unnecessary here, as only the length of the normal is used and not the
direction. Flipping the normal does not change its magnitude and therefore is
unnecessary in this case.
This allows to include script_instance.h directly in the
generated gdvirtual.gen.inc, and remove excessive includes
from the codebase.
This should also allow Resource to use GDVIRTUAL macros,
which wasn't possible previously due to a circular dependency.
GDScript has the following built-in trigonometry functions:
- `sin()`
- `cos()`
- `tan()`
- `asin()`
- `acos()`
- `atan()`
- `atan()`
- `sinh()`
- `cosh()`
- `tanh()`
However, it lacks the hyperbolic arc (also known as inverse
hyperbolic) functions:
- `asinh()`
- `acosh()`
- `atanh()`
Implement them by just exposing the C++ Math library, but clamping
its values to the closest real defined value.
For the cosine, clamp input values lower than 1 to 1.
In the case of the tangent, where the limit value is infinite,
clamp it to -inf or +inf.

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.
A common bug with using acos and asin is that input outside -1 to 1 range will result in Nan output. This can occur due to floating point error in the input.
The standard solution is to provide safe_acos function with clamped input. For Godot it may make more sense to make the standard functions safe.
