Sergey Sharybin 7dea18b3aa Tracking: Store lens principal point in normalized space 
This avoids need to do special trickery detecting whether the principal
point is to be changed when reloading movie clip. This also allows to
transfer the optical center from high-res footage to possibly its lower
resolution proxy without manual adjustment.

On a user level the difference is that the principal point is exposed in
the normalized coordinates: frame center has coordinate of (0, 0), left
bottom corner of a frame has coordinate of (-1, -1) and the right top
corner has coordinate of (1, 1).

Another user-visible change is that there is no more operator for setting
the principal point to center: use backspace on the center sliders will
reset values to 0 which corresponds to the center.

The code implements versioning in both directions, so it should be
possible to open file in older Blender versions without loosing
configuration.

For the Python API there are two ways to access the property:
- `tracking.camera.principal_point` which is measured in the normalized
  space.
- `tracking.camera.principal_point_pixels` to access the pixel-space
  principal point.

Both properties are not animatable, so there will by no conflict coming.
