Support passing operator to invoke on activating or dragging an item

An annoyance is that the operator names have to be passed to the template which
makes the already long argument list even longer.
Thought about a couple of ways to do this, unfortunately this is the only
decent way to do this that I see. There's also no way to pass operator options
currently.

Getting the handling to work correctly took some effort, and the code is not
exactly nice.

Note that even though we activate the item when calling the custom drag
operator (helps indicating the pose being blended for example), we only call
the drag operator then, not the activate one. They are never executed both.

Also note that this won't compile right now, I'll have to commit some changes
to master first.

Add utilities to temporarily append asset IDs

Uses the new `BLO_library_temp_xxx` functions, but deals with all the asset
specific file path building. This is a reasonable utility for the asset system
to have, it will probably be needed by more asset types than IDs.

Require identifier for asset view template usages

Needed if we want to support multiple different asset views in future.

Allow getting asset library and active asset handle via context

`CTX_wm_asset_library()` returns the active asset library from the workspace,
or the the Asset Browser one while inside that. The active asset handle is set
by the Asset Browser and the asset view UI template so that operators executed
via the template can access it.

Cycles: Cleanup, mark argument as unused

Fixes strict compiler warning.

Cycles: Switch copy_to_gpu_display from Task to Queue

Cycles: Avoid memory allocation on every copy_to_gpu_display()

Affects the PathTraceWorkGPU. From the measurements on own desktop it
is about 10% faster on the very simple scene with 32 samples.

Technically, this potentially increases peak GPU memory usage, but
hopefully by not so much and that the performance gain worth it.

Cycles: Update comment in the GPUDisplayParams

Make it explicit that display parameters are not aware of the
resolution divider.

Cleanup: Remove extra if

Add new node tree type for nodes inside attribute processor group

Cleanup: Use C++ vector and matrix types

Cleanup: More unused includes

Cleanup: Whitespace

Remove more unused includes, use C++ style for loop
