A new ECM service was introcuded in changeId
I831391e4437b51b3312b5273a2360bd029a3d8ee.
We begin calling it, and update/cleanup method signatures to match.
Note: There are two feature flags:
1. enhancedConfirmationModeApisEnabled - read only, protects the
mainline API.
2. extendEcmToAllSettings - runtime - gates calls to the above APIs.
We use both so we can ramp up in teamfood as needed.

If OP_ACCESS_RESTRICTED_SETTINGS is rejected, it means accessibility page
for that app is gray out and app info won't show "unlock restricted settings menu"
If OP_ACCESS_RESTRICTED_SETTINGS is ignored, it means accessibility page
for that app is gray out, but app info shows "unlock restricted settings menu"
If OP_ACCESS_RESTRICTED_SETTINGS is allowed(default), it means users can
access accessibility page for that app.
OP_ACCESS_RESTRICTED_SETTINGS will be changed to ignored if user visited
the restricted settings dialog.
OP_ACCESS_RESTRICTED_SETTINGS will be changed to allowed if user passes
the confirmation screen.
