b35264ad95 Fix AABB Ray intersection - return inside 
* Separates find_intersects from test_intersects for rays, and wraps the former.
* Changes parameter name to "r_intersection_point".
* Fixes broken old version which returned per axis t.
* Returns whether the ray origin is within the AABB.
* Returns intersection point when origin outside.
* Returns "backtracking" intersection point when inside.
* Returns sensible normal when inside.
* Returns valid results on borders.
* Returns robust results dealing with floating point error.

8747c67d9e Fix potential integer underflow in rounded up divisions 
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.

528a76486c Add inverse hyperbolic functions asinh(), acosh() & atanh() 
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.
