Cleanup: Modernize iter.

Cleanup: Removed commented out code.

Cleanup: Remove unimplemented declarations.

Implement quality setting based on UI slider

Pose library: remove invalid flags

The wrong flags were used, and it works fine without flags as well.

No functional changes.

LineArt modifier UI tweaks.

LineArt: Fix UI for misused remove_doubles and allow_overlapping_edges.

Fix T86124: Self-hosting external libraries packages

Allow downloading of source packages of Blender's dependencies, so that
it's easier to provide a "full source archive" that contains the blender
source + all dependencies archives. A `make` command for this will be
introduced soon.

This changes the deps builder slightly to be more flexible with the
origin of our source packages.

To support this a new CMake variable has been added called `PACKAGE_DIR`
where all sources archives will be stored.

default: a directory called `packages` in the build folder.

alternative-default: if a directory called `packages` exists in the
blender source folder that will be used. This is to support the "full
source archive" use case.

The download phase have been moved from the build phase to the configure
phase. Configure will download all sources validate the hashes while
downloading.

All `[depname].cmake` files have been changed to take a local
`file://[path_to_local_tarball]` path rather than a remote URI.

A second requirement was that there needed to be an option to grab the
sources from the blender SVN mirror rather than upstream. For this an
option has been added PACKAGE_USE_UPSTREAM_SOURCES (default ON). The
exact location in SVN still needs to be worked out, I tested with my
local webserver and codewise it checks out. The path that is in there
currently will not work (given there is no mirror there yet).

To build this mirror our local package caches can be used.

Merge branch 'ui-asset-view-template' into asset-browser-poselib

Fix T86168: Add primitive Grid. Wrong number of subdivisions

Changes to increase subdivision by one along both axis (X and Y)

For example with x_segment = 3 and y_segment = 3.
There should be 16 vertices ((3 + 1) * (3 + 1)) for correct
number of subdivisions. Currently they are 3 * 3 = 9 vertices.

Ref D10699

Store active asset library at workspace level

The Asset Browser still has its own active asset library. But for the UI
(e.g. the asset view UI template), there is one active asset library per
workspace now. This is needed because for technical reasons the property
has to be registered in C, ideally you could just register it as custom
property for any use-case and pass that to the asset view template.
Since this isn't possible, an active asset library per workspace seems
reasonable.

Improve proxy building performance

There are minimal changes to current code:
- Use h264 codec for output
- Specify number of threads for encoding to be same as system thread count
- Specify same nuber of threads for decoding. This may work only with some codecs(only h264 tested so far), but performance gain in encoding improves overall performance by big margin still. I have tested variety of codecs, and all were transcoded properly.

This is much simpler and straightforward patch than previous two, and this was in fact first thing I have tried to do in the beginning, but there was no improvement unless I have removed following lines:
```
rv->c->thread_count = BLI_system_thread_count();
rv->c->thread_type = FF_THREAD_SLICE;
```

I am not even sure how I found that these two lines were problematic.

VSE: Automatic proxy building

Add `Proxy Setup` enum to user preferences with 3 choices: Manual, For Added strips and Automatic.
With `For Added strips` Only build proxies when adding movie strips.
With `Automatic` setting, proxies are built when preview size changes as well.

TODO:
- Decide what to do when workspace has multiple previews with different preview sizes. See `seq_get_preview_size()`
- Solution may be to change current design to allow only one size or just build multiple sizes.

Additional possible improvements:
- Cancel running job if preview size is changed while building proxies
- Use proxy of different size while building proxies for new size. it would be best to do after some refactoring, so in separate patch.

VSE: Simplify proxy settings

- Remove Full Render size from VSE preview size. Use just 100% instead
- Add Use Proxies checkbox to control whether proxies are used globally
- Move preview size to top so it is most prominent
- Set default to 100% preview size and use proxies (could be separate patch as well)

Design task: T85469

{F9735445}

No change has been done to individual strip setting as users may need to turn proxies on/off individually.
I think it would be best if size selection will be managed when automatic proxy building is enabled. In that case proxy panel can be simplified a lot. This is probalby better to leave for separate patch
