Add memory profiler.

This adds two dump command, bazel dump --rules and bazel dump --skylark_memory.

dump --rules outputs a summary of the count, action count, and memory consumption of each rule and aspect class.

dump --skylark_memory outputs a pprof-compatible file with all Skylark analysis allocations. Users can then use pprof as per normal to analyse their builds.

RELNOTES: Add memory profiler.
