Maya Lekova 6fa780ffdc Revert "[sparkplug] Change bytecode offset mapping and introduce iterator." 
This reverts commit a8b61ef521.

Reason for revert: Looks like it breaks GC stress bot - https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64%20GC%20Stress%20-%20custom%20snapshot/35880/overview

Original change's description:
> [sparkplug] Change bytecode offset mapping and introduce iterator.
>
> Previously, we recorded pairs of (bytecode offset, sparkplug pc) to
> create a mapping of bytecode offset <-> sparkplug pc.
> These pairs were only recorded after builtin/runtime calls.
> In preparation for deoptimizing to Sparkplug, we need a more precise
> mapping.
> With this CL, we record positions for every bytecode. Instead of storing
> a pair of (bytecode offset, sparkplug pc), we store only the pc,
> calculating the bytecode offset from the index in the mapping table.
> For easier use an iterator to access the mapping is introduced.
>
> Drive-by: Reduce sampling interval in cpu-profiler cctest to get rid of
> flaky failures.
>
