Blender menu:
- Move Preferences to the top as it is used often.
- Introduce two new sub-menus
- About - links from Help menu, plus link to license section in blender.org
- Support Blender - dev fund, store, they used to be in Help menu.

Help menu:
- Add links to Tutorials and Support section in blender.org
- Add link to Developer Documentation (wiki)
- Always show Python API Reference link

Tweak API to support adding evaluated meshes to main database

One of the usecases is to create mesh from an object is a manner similar to
how Apply Modifiers does it, and have it in the bmain so it can be referenced
by other objects.

This usecase is something what went unnoticed in the previous API changes, so
here is a followup.

Summary of changes:

* bpy.meshes.new_from_object() behaves almost the same as before this change.
The difference now is that it now ensures all referenced data-blocks are
original (for example, materials referenced by the mesh).

* object.to_mesh() now creates free-standing Mesh data-block which is outside
of any bmain. The object owns it, which guarantees the memory never leaks.

It is possible to force free memory by calling object.to_mesh_clear().

Cleanup: pep8 & remove odd empty string addition

EEVEE: Viewport Rendering TAA

EEVEE assumed that the OGL renderer did FSAA, as the FSAA was removed we
needed to revalidate this assumption. The temporal sampling only inited
the matrices during init phase. As now we need to update the matrices
for every sample rendered the code for updating the matrices was
isolated in a new function `EEVEE_temporal_sampling_update_matrices`.

Revert "Tests: speed up render tests by running multiple in the same process"

This makes finding the crashing tests harder, reverting until there is a
better solution.

Depsgraph: Make depsgraph.update() safe for threading

This is same as view_layer.update() is doing.

UI: Tweak naming in Sequencer View menu to match 3D View

Cleanup: rename IDP_FreeProperty_ex to IDP_FreePropertyContent_ex

This was missing from rBdb5120603f.

UI: Match Sequencer Safe Areas with similar Camera Properties panel

Refactor: Simplify ID Property freeing

This also makes `IDP_CopyProperty` the "opposite"
of `IDP_FreeProperty`, which is what I'd expect.

Two refactoring steps:
* rename IDP_FreeProperty to IDP_FreePropertyContent
* new IDP_FreeProperty function that actually frees the property

GPencil: New filter in Onion by keyframe type

This new filter allows to select only some type of keyframe (keyframe, breakdown, etc).

This was a request of artists that are used to work with other 2D softwares.

Also some cleanup to remove aninmatable option to some properties.

UI: Video Sequencer sidebar overhaul

- Use single column layout
- Move the rather obscure Backdrop toggle into the View menu
- Use correct units for Crop and Offset (pixels)
- Re-organize the sidebar in 2 main groups: Adjust & Info

Adjust includes Compositing, Offset, Crop, Video, Color, Sound
Info includes strip name, path, start/end and other data
