Add annotation layer with the right name

When adding layers, the name of the layer is different for grease pencil object and annotation.

Annotations: Restore 3D View support for annotations (WIP)

Initial support for getting annotations to show up in the 3D
viewport again. WIP and slightly hacky, but it restores basic
working functionality so we can focus on polishing the "new" parts.

Ultimately, the way these callbacks are integrated into the
drawing loop will probably need to change. For example,
* Perhaps we might need a full overlay engine for this one case
(as for motionpaths), though that may also be overkill, and would
further split the code in different places.
* The draw order (relative to manipulators) needs review. It probably
should be below both sets of manipulators, not sandwiched between them.

Other notes:
* For this to work, we currently need to use the original (non-evaluated)
scene data, or else we don't get the newly drawn strokes, as the
scene->gpd stuff isn't copied by COW yet.

Annotations Keymap: Restore D-RMB for eraser

Cleanup: Remove redundant code + note some code issues to fix

Set annotions drawing mode always on top

The annotations must be visible on top of any other object in the scene.

Cleanup: Fix comments

Initial implementation of Shader FX (effects).

Now, the FX are used only by grease pencil object, but the design is ready to be used for other object types.

These FXs replace the old VFX modifiers, that were removed during the first steps of the greasepencil-object merge review.
The new implementation is fully separated of modifiers and with its own management modules.
