Adds fixed timestep interpolation to the rendering server (2D only).
Switchable on and off with a project setting (default is off).

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.
