Reverts: flutter/flutter#150287
Initiated by: jtmcdole
Reason for reverting: other memperf tests don't wait for or send a TAPPED; so they fail.
Original PR Author: jtmcdole

This change reverts the following previous change:
Initial tap is missing sometimes; either its never delivered or it is delivered before gesture controller is hooked up.
1: Update the two perf tests to output when TAPPED is received
2: Update the MemoryTest to keep tapping while waiting for TAPPED
Tested on devicelab:
* setting iterations=1
* removing the timeout before READY
* running tests in a while loop
Before this change, you could get the test to hang often. After this change you'll see "tapping device... [x]" where x is the counter.
Fixes #150096
