Fix T67832: Camera Background Images View Transform

This patch will apply the view transform when a movie clip is used as
camera background image. It does this by rendering the image in the
color buffer when it needs the view transform. For other images it uses
the overlay buffer.

Fix T81775: Object Disappears During Texture Painting

Issue was that the `tris_per_mat` are not created when the first batch is drawn
during select operator and then is not created when needed by the workbench pass
since they are not tracked by mesh_buffer_cache_create_requested.

This change will create the `tris_per_mat` just in case they are needed later.

Cycles: fix multithreading issue introduced in previous commit

The issue is that the shaders are stolen from the original Geometry by
the temporary Geometry used to accumulate data, but the main thread
still needs them for syncing the attributes.

So make a copy of the shader array to preserve the data on the original
Geometry.

Modifiers: return empty mesh in case of error in Volume to Mesh modifier

Passing on the original mesh does not really make sense.
For that one should simply disable the modifier.

Fix T82393: Volume to Mesh modifier with sequence fails during rendering

The issue was that the volume for the current frame
might not have been loaded already by the time the
modifier runs.

The solution is simply to make sure that the volume
is loaded. This is similar to the Volume Displace modifier.

Fix T82292: Set encoding for keymap export to UTF-8

Keymaps have previously been exported with an encoding dependent
on the current system locale. This caused issues when the
keymap contained non-ASCII characters, for instance in a string
property for an operator.

Cycles API: encapsulate Node socket members

This encapsulates Node socket members behind a set of specific methods;
as such it is no longer possible to directly access Node class members
from exporters and parts of Cycles.

The methods are defined via the NODE_SOCKET_API macros in `graph/
node.h`, and are for getting or setting a specific socket's value, as
well as querying or modifying the state of its update flag.

The setters will check whether the value has changed and tag the socket
as modified appropriately. This will let us know how a Node has changed
and what to update, which is the first concrete step toward a more
granular scene update system.

Since the setters will tag the Node sockets as modified when passed
different data, this patch also removes the various modified methods
on Nodes in favor of Node::is_modified which checks the sockets'
update flags status.

Fix assert on mouseover of blocks not using the layout system

When there was an active button in the "old" block from the last redraw,
this code tried to replace its pointer in the new block's button groups.
But in cases like the outliner or file browser, there are no groups
because the block doesn't use the layout system at all. This commit
just tweaks the assert to check whether there are any button groups.

CMake: remove -fmacro-prefix-map from build-info

Quotes caused build-info to fail,
remove these flags since they're not necessary.

Cleanup: make format

Fix T63495: Add torus changes size each time when unit scale != 1.0

This matches behavior in WM_operator_view3d_unit_defaults.

Cleanup: Add BLI prefix to some BLI_noise functions
