sweet: add support for execution traces and refactor profile plumbing

This change does a lot at once, but it's mostly refactoring. First, it
moves most of the profile abstraction out of benchmarks/internal/driver
and into a new shared package called diagnostics. It also renames
profiles to diagnostics to better capture the breadth of what this
mechanism collects. Then, it adds support for turning on diagnostics
from configuration files. Next, it adds support for generating
additional configurations to capture the overhead of collecting
diagnostics, starting with CPU profiling. Lastly, it adds support for
the new Trace diagnostic.

(This change also fixes a bug in go-build where Linux perf flags weren't
being propagated.)

In the future, core dumps could easily be folded into this new
diagnostics abstraction.

For golang/go#57175.
