4805a54525 BLI: Math: Move rotation types template out of math::detail
The reasoning is that the detail namespace is not to be used
outside the module itself. But one might want to use different
number types with these templates.

The `Base` suffix was chosen in order to be consistent with `MatBase`
and `Vector` naming convention.

28a581d6cb BLI: Rotation C++ API
This patch re-implement the whole C rotation API into a more type
oriented C++ API. See the #104444 design task for more details about
the goals.

The list of C to C++ equivalent syntax can be found attached.

This adds `AngleRadian`, `AngleCartesian` and `AngleFraction` as
different angle types with the same interface. Each of them have
specific benefits / cons. See inline documentation for detail.

This adds `Axis` and `AxisSigned` class wrapped enums to increase type
safety with axes selection.

This adds `CartesianBasis` to represent orthonormal orientations.

Added a weight accumulation to dual-quaternions to make normalization
error proof. Creates the overhead of summing the total weight twice
(which I think is negligible) and add an extra float.

Named the dual-quaternion `DualQuaternion` to avoid naming ambiguity
with `DualQuat` which come up quite often (even with namespace).
