Germano Cavalcante 9a6fd69993 Fix T87947: Trasnform: Keyboard input uses view orientation 
When activated in modal, `translate`, `resize`, `rotate`, `shear` and
`edge_rotate_normal` use a different orientation than the set in scene.

This orientation needed to match since some of these modes can be switched
during operation.

The default orientation for these modes was `V3D_ORIENT_VIEW`.

And this changed when finishing the `translate` and `resize` to
`V3D_ORIENT_GLOBAL`.

But this could cause inconsistencies when inputting values from the
keyboard.

The solution now is to change the orientation when you change the mode.

---
Note: Although the user can expect the value entered to reflect the
orientation set in the scene, it would require a lot of changes and would
not be really useful.
