Compositor - Sidebar - Options - Float checkboxes left (and remove legacy features from documentation)

[Draise14]

This panel is making moves to the GPU compositor, now moved out of experimental in next merge. But with that things got mc-gucky and needs a bit of love. Documentation also needs to be stripped back down.

• Compositor: Remove Two Pass option

There are few issues with the logic and implementation of this option:

• While the first pass is faster in the terms of a wall-clock time, it
  is often not giving usable results to artists, as the final look of
  the result is so much different from what it is expected to be.

• It is not supported by the GPU compositor.

• It is based on some static rules based on the node type, rather than
  on the apparent computational complexity.

The performance settings are planned to be moved to the RenderData, and
it is unideal to carry on such limited functionality to more places. There
are better approaches to quickly provide approximated results, which we can
look into later.

• Compositor: Remove Render/Edit Quality setting

The setting was only affecting some of the blur operations, which
does not typically results in a measurable performance boost in real
compositor setups.

For the simplicity of settings on user level remove setting which
potentially makes compositor output worse, without much benefit.

There are better ways to gain performance, like compositing on a
lower resolution, exposing "preview" as an input to the node tree
(similar to the geometry nodes) etc.

• Compositor: Remove quality setting from DNA and UI

It was meant to be included into the previous commit in the area,
but was forgotten due to some technicalities.

Also remove the DisplaceSimpleOperation, which is now not used.

• Compositor: Move Execution Mode and Precision from bNodeTree to Scene

This allows to expose these settings in the Performance panel in the
render buttons. Also moves compositor-specific options away from the
generic node tree structure.

For the backwards-compatibility the options are still present in the
DNA for the bNodeTree. This is to minimize the impact on the Studio
which has used the GPU compositor for a while now. They can be
removed in a future release.

There is no functional changes expected.
