Michael Anthony Knyszek 43ffe2a892 runtime: add execution tracer v2 behind GOEXPERIMENT=exectracer2 
This change mostly implements the design described in #60773 and
includes a new scalable parser for the new trace format, available in
internal/trace/v2. I'll leave this commit message short because this is
clearly an enormous CL with a lot of detail.

This change does not hook up the new tracer into cmd/trace yet. A
follow-up CL will handle that.

For #60773.
