[debug-wrapper] Adapt tests, breakpoint.actual_location

Browse Source 
Adapted various tests to restrictions of inspector protocol:

* osr-typing-debug-change: Don't set function variable value.
* debug-evaluate-locals: Add variable introduced by eval, run typeof
  inside evaluate().
* regress-419663: Don't set duplicate breakpoints.
* regress-crbug-465298: Compare against function name instead of value.
* regress-crbug-621361: Make evaluate return string results.
* debug-script: Various counts were off due to new way tests are called.
                Added new inspector script type.

Breakpoints now contain the actual break position, and remote object
reconstruction has been extended a bit.
