Change flag internalAddSemanticForOnTap default value to true (#153193)

This is a follow up on flutter/flutter#152526 

1. Make changes with an additional parameter ( bool internalAddSemanticForOnTap = false) (flutter/flutter#152526 )
2. Send regular CLs in google3 to pass internalAddSemanticForOnTap: true, and update the tests / text goldens 3. accordingly.  g3 fix sent:  cl/661353802
3. Send a PR to flip the default value to true. (This PR)
4. Send CLs internally to remove internalAddSemanticForOnTap: true.
5. Send another PR to remove the now-redundant internalAddSemanticForOnTap flag.
(<----This PR is step 3)
