GPencil: Fix On/OFF buttons for VFX

As the VFX was using if the mode was render, and this mode was shared with the shading type, the Viewport ON/OFF button was not working as expected.

Now, the VFX use a is_viewport control and the is_render is not used.

GPencil: Change Weight Paint to Blend values

Before, to substract weights it was necessary to press Ctrl key, but now the weight paint work equals to mesh weight paint blending weights and the Ctrl key is not used anymore.

This also allows to define the target weight easily.

GPencil: Add rotation effect to Blur and change default value

undoexp: add message when having to actually re-allocate ID during undo.

GPencil: Rename some params in Material panel

GPencil: Fix Duotone Colorize error in Panel

The props were using old BITONE name mode.

GPencil: Convert Blur size to float and avoid unedeed passes if size is 0

GPencil: Change Blur VFX panel and remove unused code

Cleanup: Rename anchor_object -> base_pose_object

The term "anchor" is already used differently in the context of XR, so
rather avoid the ambiguity.
