Remove usages of bugfix flag cleanup_accessibility_warning_dialog.
Flag has been in Trunkfood for over a month.
Includes one mechanical refactor to move a method from a now-removed
file into a private method in the class that uses it: createDisableDialog
(This flag guarded a preliminary cleanup and minor bug fix for
b/303511250, but the actual feature for b/303511250 is tracked in a
different flag 'skip_accessibility_warning_dialog_for_trusted_services')
Bug: 303511250
Test: existing tests in Presubmit (no change to behavior)
