Revisit tracing strategy

The current state of tracing in hyperlight is a bit all over the place. We should have:

Less fine grained tracing: Right now many irrelevant small helper functions are being traced. We should consider only covering our APIs
Include guest calls in tracing spans
Revisit which function parameters should and shouldn't be traced.
Revisit tracing log levels

I suggest that we only place trace attributes on pub functions, that should reduce the overhead/noise

I think a better parent for this issue is #375
