Remove logic of polling liveness of compiled code.

Data shows the current logic is having too many misses by
deleting baseline compiled code which could still be useful.

Reduces jank on compose view scrolling for 20 seconds, average of 50
runs:
- For Go Mokey:
    - Before: ~433 frames drawn / ~18.47% janky frames
    - After:  ~485 frames drawn / ~17.02% janky frames
- For Pixel 8 pro:
    - Before: ~2428 frames drawn / 1.20% janky frames
    - After:  ~2433 frames drawn / 1.02% jank frames
