Using transformed event for standard gesture detector

TouchExplorer uses raw event in both a11y and standard gestures
detection, but transformed event in following movement. This
inconsistency causes significant difference of distance between
their locations when screen is magnified and long press would fail.
Passing transformed events for standard gesture detector instead.

Bug: 67378068
Test: manually test if double tap and hold works while Talkback
