Cycles: Fix optimal BVH selection.

Grease Pencil dat files fix

The ones I previously commited were done with Inkspace 0.92.2
But apparently this renders some parts of the icons transparent.

For example, the tip of the new grease pencil pencil icon.

Grease-Pencil: Fixup for icons

I tried to cleanup the .svg but I overdid it a bit

Cycles: Replace use_qbvh boolean flag with an enum-based property

This was we can introduce other types of BVH, for example, wider ones, without
causing too much mess around boolean flags.

Thoughs:

- Ideally device info should probably return bitflag of what BVH types it
supports.

It is possible to implement based on simple logic in device/ and mesh.cpp,
rest of the changes will stay the same.

- Not happy with workarounds in util_debug and duplicated enum in kernel.
Maybe enbum should be stores in kernel, but then it's kind of weird to include
kernel types from utils. Soudns some cyclkic dependency.

Collections/Layer cleanup: Remove placeholder for de/select objects

No need for placeholders bloating the source code. They can come back once
we decide to implement them.

Collections/Layer cleanup: Remove all reference to filter objects

This was not implemented yet. So it's a bit pointless to have all this
placeholder code around without any functionality coming out of it.

Collections/Layer cleanup: Remove TODO_LAYER_OVERRIDE from most places

This was originally a good idea. However we will need to pay special attention
to this when doing the dynamic overrides anyways. The placeholders won't be
enough to spare us that job.

That said I left the ones on layer.c because we are actually calling these
BKE_override_*_add() functions from doversion, yet they don't do anything.

T53831: Fixed vertical line alignment & expand Collection and Scene buttons position.

This was fixed in master with commit 9d873fc3debe0. However, this fix never made it to 2.8.
(The following merge (a96008f3aae2) did not import the fixes.)

Note: This fix is ment to fix the alignment problem.
I don't know if other parts of the code not merged are interesting or not.

But if they are, they should be tackled separately.
