[interpreter] Switch profiler to use frames for OSR.

This switches the interface of the runtime profiler to use frames as
opposed to functions for performing on-stack replacement. Requests for
such replacements need to target a specific frame. This will enable us
to activate bytecode as well as baseline code for the same function.

The existing %OptimizeOsr runtime function also had to adapted and now
takes an optional stack depth to target a specific stack frame.
