Fix report logging

- do not return NULL from BKE_reports_sprintf, it is too hard to handle memory free-ing
- fix: convert clog info to verbose

Add verbose log severity

- it is common practice to have separated info and verbose log
- verbose log is always with code
- convert LOG_INFO with level higher than 1 to LOG_VERBOSE

Cleanup: fix comment

Apply Modifier: support applying as shape key and keeping the modifier.

This can be useful to save the result of a cloth simulation as a
shape key without destroying the simulation, so it's possible to
e.g. re-run it to get other shapes, or simply use the new shape
key to start the simulation already in a draped state.

It also makes sense to allow applying as shape key even when the
mesh is shared, because the operation itself just adds a shape
key. To support this, split the apply operator into Apply and
Apply As Shapekey so that they can have different poll callbacks.

Fix T78324: Different Sky Texture results between CPU and GPU

The problem here was numerical precision: The code calculates the angle between
sun and view direction, and the usual acos(dot(a, b)) approach for that has
poor numerical performance for almost parallel angles.

As a result, the generally tiny difference between floating point computation
between CPU and GPU was enough to make the sun vanish at different radii,
causing different results.

The new version fixes the difference by making the computation much more robust
on both platforms.
