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.
This cleans up a bit of duplicated code and some confusion about
what was culled and what wasn't.
Now everything is culled based on the given object pointer.
If the object pointer is NULL there is no culling performed.
This type of indices is not natively supported on modern GPU and
gives warning on some implementation. The memory savings it
provides is also quite minimal and unlikely to be visible on
nowadays hardware.
This remove some uneeded struct members and makes primitive
restart always enabled by default. This can be broken by addons
if they are not careful enough but many other states have this
problem.
Also leverage GL_PRIMITIVE_RESTART_FIXED_INDEX if
ARB_ES3_compatibility is supported. This removes all API calls
to change restart index depending on indices length.
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`.

three issues here:
- when curves had multiple nurbs, the active vert is per nurb
[curve_create_edit_data_and_handles() wasnt taking that into account]
- code could go wrong when points where hidden
- upon selection, tag curve ID_RECALC_COPY_ON_WRITE for batch cache
update

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.
Adding a constant yields quadratic time complexity which can
have quite a big impact on some scenes.
I used the file from T64901 for testing.
In the test file, the time it took to execute `wm_draw_update`
changed from `0.60s` to `0.51s`.

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 to simplify the usage of Volumetrics.
Now it automatically detect if there is any Volumetric material in the
view and allocate the needed buffer if any.
