Change UI panel registration order

This change is to keep the Tools tab on top because if the grease pencil panel are register at the end, the Tools tab change to end.

New icons for Grease Pencil sculpt brushes

In order to keep consistency, we have added icons to GP sculpt brushes similar to object sculpt

Implement lock axis in Sculpt grab brush

This is the first implementation to lock the axis while sculpt. In some extreme angles the result is not perfect, so maybe need a review.

We keep in this way while we found a better approach, maybe using the reprojection of the point as it is done when draw new strokes could work better.

Add missing UI options for sculpt and paint mode

The onion and mask buttons can be used in sculpt mode also.

Fix only_render for GP object

For GP objects, the strokes must be drawn in all cases. When only render is enabled, only the pivot point is hidden, but not the strokes.

Now the user can select other objects for paint or sculpt.

In edit mode is not possible in order to keep UI coherence

The cursor did not return to paint after using eraser

Replace Erase Keymap to LeftMouse + Alt

In order to keep consistency with Blender, the right mouse is used to select objects, so the eraser must use a different key.

This can be changed after more workflow tests
