Alex Chau 1e767a6ecc Refine logs for debugging TaplTestQuickStep.testOverviewActions on cf_foldables 
- The failure is not reproducible locally, thus requires adding logs and check ATP result
- Removed some redundant logs
- Changed to log at VERBOSE
- Added extensive logging to all visibility/enable/alpha setter of ActionsView

Bug: 193125090
Test: Manual
Change-Id: I5b449a7f86ea4cef65e0e46de4b389deef9f53f3
