This PR adds support for the busperf analyzer, which measures bus-interface stalls in digital designs
from a VCD trace. It generates the YAML bus config busperf needs to interpret that trace, derived from
an XLS codegen signature. It adds one Bazel rule,
busperf_yaml, and extends signature generation so ablock's signature recursively embeds its children's, so internal proc-to-proc channels are covered in
the config too, not just the external interface.
Extracted from #4633, which also added
busperf_analyze(running busperf against the VCD with thisconfig to produce a report) and a worked example. Those are left for a follow-up PR.
