Implemented callstack capture flow for a unit test

This adds parts of the infrastructure required to display the callstack in the ui. And adds a test to verify the basic capturing concept works.

The implementation requires utilizing rstack_self crate to the capture which in turn required helper crates to wrap its functionality for ease of use.
