Earlier we used the same interrupt budget always and waited for higher
number of ticks when tiering up from Turboprop to TurboFan. On some of
the real world pages this adds a reasonable overhead for processing
these interrupts. This cl sets the interrupt budget to a higher value so
there are fewer interrupts. This cl:
1. Sets the interrupt budget on feedback cell to
FLAG_interrupt_budget * scale factor when we install optimized code.
2. Resets the budget to FLAG_interrupt_budget when there is a
deoptimization.
3. Updates the runtime profiler to remove the scaling of number of ticks
needed for optimization when tiering up from TP to TF.

On sheets benchmark, we spend 40-50ms when servicing interrupts from
Turboprop code. This change brings it down to ~7ms. We also see
improvements on other pages.
