Metal: Cache render pipelines at the context level

Cache Metal render pipelines in a new mtl::PipelineCache which lives
at the context level. This allows us to clean up unused pipelines from
programs that are not actively used.

The cache limits were chosen based on running Chromium. Without a
limit, the total number of pipelines peaks at ~200. With frequent GCs,
the active working set usually sits at ~60 pipelines.
