[PATCH 0/1] MR443: wined3d: Defer destroying Vulkan compute pipelines.

[Jan Sikorski (＠jsikorski)]

Vulkan pipelines should be destroyed only after the last command buffer using
the pipeline is done executing. Since we do not track which pipelines are
encoded into which command buffers, defer destruction until the current command
buffer finishes.

It feels unfortunate to do this from the shader backend, and introducing something
like wined3d_shader_vk etc. seems more in line with what we do with other objects.
I'm not sure that the complication is worth it in this case.
