Cleanup: Split View3D navigation code into specific compilation units 

The view3d_edit.c file is already getting big (5436 lines) and mixes
operators of different uses.

Splitting the code makes it easier to read and simplifies the
implementation of new features.

/* Avoid Gimbal Lock
*
* Even though turn-table mode is in use, this can occur when the user exits the camera view
* or when aligning the view to a rotated object.
*
* We have gimbal lock when the user's view is rotated +/- 90 degrees along the view axis.
* In this case the vertical rotation is the same as the sideways turntable motion.
* Making it impossible to get out of the gimbal locked state without resetting the view.
*
* The logic below lets the user exit out of this state without any abrupt 'fix'
* which would be disorienting.
*
* This works by blending two horizons:
* - Rotated-horizon: `cross_v3_v3v3(xaxis, zvec_global, m_inv[2])`
* When only this is used, this turntable rotation works - but it's side-ways
* (as if the entire turn-table has been placed on its side)
* While there is no gimbal lock, it's also awkward to use.
* - Un-rotated-horizon: `m_inv[0]`
* When only this is used, the turntable rotation can have gimbal lock.
*
* The solution used here is to blend between these two values,
* so the severity of the gimbal lock is used to blend the rotated horizon.
* Blending isn't essential, it just makes the transition smoother.
*
* This allows sideways turn-table rotation on a Z axis that isn't world-space Z,
* While up-down turntable rotation eventually corrects gimbal lock. */
