Cycles: Correction to previous commit

Committing directly because those are rather trivial fixes for something
what got broken rather badly.

- Fix compilation error in debug mode.
- Fix non-combined passes in viewport.
- Fix adaptive sampling for final rendering.

add typed mutable virtual array

Cycles: Shorten function name

It is inside of viewport parameters, no need to repeat this in the
function name.

Cycles: Clarity comment in integrator synchronization

Cycles: Use early output and avoid over-commenting

Cycles: Move use adaptive sampling flag to integrator

Makes it closer to the rest of the adaptive sampling settings and
allows access from Scene.

The current downside is that rendering does need an extra integrator
synchronize call which will be removed by a followup development.

There should be no functional changes.

Cycles: Use range based loop

Cycles: Add idea of automatically created passes

Those are the opposite of the ones which are configured by users in the
interface.

Currently unused, preparing for taking over of automatically creating
adaptive sampling passes.

Cycles: Simplify delayed reset API

Avoids passing arguments around.

Currently no functional changes, just simplifies some things in the
future in the terms of naming.

Cycles: Automatically create adaptive sampling and viewport passes

Fixes non-working adaptive sampling in the viewport: the missing passes
was the only reason for that.

Now the synchronization code is supposed to store passes in Scene and
never provide them via BufferParams.

The passes are assigned to the BufferParams when dopin session reset.
This way the rendering code has access to proper stride information.
In the future we can remove passes from BufferParams and pre-compute
strides and offsets before passing the BufferParams down the road.

Had to explicitly remove the passes: can not rely on the fact that the
synchronization code overrides passes in scene as this is not the case
for viewport rendering.

Cycles: Remove baking tile reading code

The baking needs to be brought back in a better shape.

Removing the code which is to be re-written to simplify some upcoming
development.

Cycles: Remove passes from BufferParams

Now it is the Scene which is the source of truth for passes.

The RenderBuffers will store pre-calculated offsets and strides
which are set once when the passes are known. There are few things
which are good:

- Data is no longer duplicated, is clear where passes are to be
accessed from.
- Code which sues BufferParams can access offsets and strides
directly, without re-calculating anything.
- DenoiserBuferParams are removed, since it does not bring any
new functionality.

Some downsides:

- Construction of new RenderBuffers is to be done with a bit more
care now.

- Passes needs to be passed to `get_pass_rect`.
A bit annoying, and almost like the RenderBuffers is the wrong place
for this function.

- `set_pass_rect` is disabled for now. Is unclear whether it will be
needed in the future, and what would it final placement be.
