Add a command line argument --gpu-vsync on/off/auto.
Prefer command line arguments for GPU settings,
as it means the value is error checked and set when Blender starts.
Also refactor GHOST_Context to take a parameter argument which
includes the stereo-visual & debug arguments and includes the newly
added vsync setting. This makes it possible to add GPU context
parameters more easily in the future.
It also removes redundant parsing & setting the VSync setting for
off-screen contexts.
Changes to recent PR !143049.
Ref !144473
Update the `ShaderCompilerGeneric` to support deferred compilation
using the batch compilation API, so we can get rid of
`drw_manager_shader`.
This approach also allows supporting non-blocking compilation
for static shaders.
This shouldn't cause any behavior changes at the moment, since batch
compilation is not yet used when parallel compilation is disabled.
This adds a `GPUWorker` and a `GPUSecondaryContext` as an easy to use
wrapper for managing secondary GPU contexts.

Pull Request: https://projects.blender.org/blender/blender/pulls/136518
Rendering animations from Python scripts via `bpy.ops.render.opengl()`
did not trigger any of the notifications in the Metal back-end to
indicate a frame had been rendered and that the associated resources
could be released. This adds a call to GPU_render_step() after each
render. For the original asset in the bug report this reduces the high
memory watermark from 30gb to 13gb for 500 frames. 13gb is likely
still too high and therefore it is likely there are additional leaks
that need to be addressed so this should only be considered a partial
fix.
