Vulkan backend has recently switched to a render graph approach. Many
code was left so we could develop the render graph beside the previous
implementation. Last week we removed the switch. This PR will remove
most of the unused code. There might be some left and will be removed
when detected.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
The current Vulkan resource management has some issues as context that
are not active can still use resources that are freed via another
context.
When this happens incorrect data can be read on the GPU and even crash
Blender. When trying to bind something that now contains other memory
pointers.
This change introduces that contexts are tracked via the device.
Context will be registered/unregistered with the device instance.
Unbinding of resources must pass the device and the device will check
all registered contexts. Binding of resources will happen via the active
context only.
On user perspective this now allowes:
- Opening/switching files
- Switching workspaces
- Switching render engines
