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.

This is in preparation to enabling --turbo-inlining by default, fixing
various issues when general purpose inlining is running against our
entire test suite.

This is a workaround to make the debugger happy about TurboFan frames
when the debugger causes frame inspection. Note that this can happen
because the debugger can be activated while there still are optimized
TurboFan activations on the stack.
