fix(render3d): a refused pipeline is not retried every draw, and an evicted chunk is freed whole

Browse source 
gvk_pipeline_fast cached only pipelines it made, so one the driver refused was attempted again on
every draw, each attempt building its key string and create structs anew; the refusal is cached
too (a Vulkan program's variants are fixed when it is made, so it would fail the same way).
stream_evict made a new chunk list per eviction and never freed the evicted chunks' records; it
compacts the list in place and frees each evicted chunk with its data.
