vk_pipeline_cache: destroy graphics pipelines unused for 9000 frames

Each built pipeline holds ~0.45 MB of driver memory and none was ever
destroyed, so it grew with every place a session went. One unused for
9000 frames is destroyed once the GPU is past it and built again from
the driver's pipeline cache (2-3 ms) if it is needed later; the
transitions between pipelines are cleared, and pipelines used this
session still go to the used list. Mario Kart World's title screen, 10
minutes: 1,714 evicted, 1,700-1,850 kept instead of a count that only
grows.
