Grease Pencil already reset the default view so the draw_manager wouldn't assert. During multi view rendering the same assert still happened. This patch will reset the default view when starting to render a new view.

Migrate old legacy code to the draw mamager/object mode. The old legacy
version did not work with wireframe. By migrating the code
to modern draw manager code we have mode control on the drawing process.
Still background images do not work with OIT, the cause seems to be that the transparent pixels are treated as background pixels.
Also There are some artifacts when working with Holdouts and DoF, this
is because the draw engines do not pass the correct alpha values.

When performing F12 render on a transparent film all solid objects where
a bit transparent. Single Pass AA and no AA passes were not visible at
all.
Issue was that the first frame was not handled correctly making these
artifacts. This commit changes the order of `GPU_state_init` and
`DRW_state_reset` so the state is correct during the first pass.
The OpenGL state was not set to blender defaults when using
`DRW_render_to_image` path. This is only used when doing F12-rendering.
Cause of changes with the `RESTART_INDEX` hair rendering was rendering
the restart_index as an actual vertex index.

Centralize logic for when to use the PBVH for drawing, fix missing tests in
mask drawing, fix missing tests for multiple windows, only do more expensive
update for all viewports at end of the stroke.
The draw manager used to determine if the view transform should be
applied by checking if the scene was not rendered to an offscreen image.
As the sequencer and texture painting needs to render to an offscreen
image with the view transform applied we need to separate the
`do_color_management` from the `is_image_render`.

More accurate determination when to draw the PBVH and when to draw the
regular mesh. PBVH drawing is done for Multires, Dyntopo and normal
sculpting with no active modifiers.

A lot of drawcalls don't use the object's properties and don't
need a dedicated DRWCallState. We allocate a unique one at
the begining and use it for all calls that uses the default
unit matrix.
Fix for GPencil and Cycles Render draw type. GPencil objects were only
shown when overlays were turned on. The cause of this is an
optimization we did to not populate any draw engine when an
external renderer was used with overlays turned off.
This will check if there is any visible GPencil object in the scene. if
so it will still perform the loop.
`DEG_id_type_any_exists` can check if any object of a certain type_id is in the
result. This check is also being used to check if there are any
visible grease pencil objects as a precheck in `DRW_render_check_grease_pencil`.

Remove the clear allocation flag as it has little impact since there should
be very few allocation per redraw.
Make BLI_memblock_alloc and BLI_memblock_iterstep much more cache efficient
removing them almost entirely from performance profiles.
This will have multiple benefit.
TODO detail benefits (culling, more explicit, handling of clipping planes)
For now the view usage is wrapped to make changes needed more progressive.
The previous fix 8a6414ed46, resolved selection picking but didn't
work for box/circle/lasso select.
- Add ED_select_buffer_utils.h for general select-buffer operations
unrelated to edit-mesh.
- Circle select still needs to cache select-id's for each update.
This is a big change that cleanup a lot of confusing code.
- The instancing/batching data buffer distribution in draw_instance_data.c.
- The selection & drawing code in draw_manager_exec.c
- Prety much every non-meshes object drawing (object_mode.c).
Most of the changes are just renaming but there still a chance a typo might
have sneek through.
The Batching/Instancing Shading groups are replace by DRWCallBuffers. This
is cleaner and conceptually more in line with what a DRWShadingGroup should
be.
There is still some little confusion in draw_common.c where some function
takes shgroup as input and some don't.
The DrawManager assumed that the first render layer was the render layer
where GP needed to render on. In viewport this is always the case as we
only have a single view layer. When rendering this can be multiple when
multiple layers are rendered and composited in the compositor.
In stead of the assumption that the first render layer is the render
layer we need to draw on, we search for the render layer with the same
name as the viewlayer.

When using multiple viewlayers and switching between them the selection
gets buggy. The reason for this is that the select_id is updated based
on the index in the viewlayer. This makes the select_id not unique as
objects might be shared or not shared at all.
This fix will update the select_id on all objects in main. This will be triggered in all the selection operators.

This is in order to create less shading group when using duplis.
Data for dupli objects keep in draw manager state until the source object
changes so retrieval is fast.
Note that this system could be extended to all meshes.
