Description
We have an instance setting, DebuggerBreakOnNextLine, which allows debugging the boot process. It is wired to Chakra and V8, but doesn't seem to effect Hermes. From feedback in teams, folks would find this functionality to be useful.

Trace how the DebuggerBreakOnNextLine instance setting is wired for Chakra and V8, then compare that path with Hermes support. Done means the setting also enables debugging during the Hermes boot process; validate the behavior across the affected engines.
