GPencil Editors API: Added utility function to be called to get Copy-on-Write evaluated copies of data

* Use ED_gpencil_get_active() for writing settings back to the original datablock
(existing callback used in most operators now)

* Use ED_gpencil_get_active_evaluated() for getting the COW-evaluated geometry
(i.e. with modifiers, etc.) applied. i.e.,
``` const bGPdata *gpd_eval = ED_gpencil_get_active_evaluated(C); ```

Code Cleanup: Clearly label which parameters are used for input/output

Cleanup: Fix indentation

Cleanup: Fix some more warnings

NOTE: For rna_GPencil_stroke_new(), the problems aren't entirely eliminated yet.
Specifically, the colorname arg is now unused - it was used in the past to
specify what color the new strokes should have.

Cleanup: Remove unused var

Revert to use again BKE_gpencil_batch_cache_dirty()

These functions were changed by error when replace dirty management by depsgraph.

The depsgraph is only valid for operators and the files included in this commit must call the function directly and don't use depsgraph tag.

Back BKE_gpencil_batch_cache_dirty function

This function was removed by error in previous commit.

Cleanup: Add new line at EOF

Remove BKE_gpencil_batch_cache_dirty()

This remove the function because is not used.

Replace DRW_gpencil_batch_cache_dirty() with DEG_id_tag_update

Cleanup. Rename material variable to "ma"

The old name "mat" could be confused with matrix.

WIP depsgraph fixes for GP and depsgraph

Still not working yet - somehow the updates aren't getting flushed yet
(perhaps COW related)

Cleanup: Indentation

Add default brush material to object materials

When draw using a brush that uses a default material, the material must be added to the object material slots if this material was not before.

Rename Grease Pencil Array Modifier to Instance Modifier

The new name is more clear and does not create confusion with 3D objects array modifier.

Fix error drawing with no object active

Cleanup: Remove redundant parameter

Fix wrong Material name

The name was using the ID type.

Fix error in Join objects

The index of the material must be stroke value + 1.

Cleanup: Remove old unused code for bGPDpalettes

This commit removes some functions not used from old bGPDpalette and bGPDpalettecolor.

These structs were used in version 2.78 and 2.79 and only keep the minimum number of functions to convert old files.
