internal: stacktrace: skip internal packages

[eliottness]

What does this PR do?

This PR refactors the internal/stacktrace package to skip modules managed by the tracer to provide a cleaner stacktrace to users.

Motivation

The default stack size is 32 and is bloated with internal code that the user does not care about

LGTM overall.

Like we discussed I think a ring buffer could be a nice addition to the frame traversal to avoid those queue/dequeue operations on large stacktraces
