[turboprop] Increase the Turboprop interrupt budget to 20*K

Currently Turboprop interrupt budget is 14*K. From finch experiments and
from the local benchmark results it seems like we can push it
back a bit. Increasing the interrupt budget for Turboprop also pushes
the TurboFan compilations given the scale factor of 10. So this cl
increases the Turboprop budget from 14*K to 20*K and TurboFan budget
from 140*k to 200*K when turboprop is enabled. The default isn't
impacted.
