[Android] Improve TalkBack support

[j-piasecki]

Description

Updates touchable components and NativeViewGestureHandler so that TalkBack is better supported:

• explicitly dispatch LONG_CLICK accessibility action from buttons when defined
• stop ignoring motion events in NativeViewGestureHandler when TalkBack is enabled
• don't activate native gesture for button when isPressed is true - this means that events are being passed through to the view, so the default flow should handle it
• updates Pressable state machine to allow optional states
• updates Pressable state machine for Android with TalkBack to rely on NATIVE_BEGIN and NATIVE_FINALIZE instead of LONG_PRESS_TOUCHES_DOWN - with TalkBack enabled, the activate action (double tap with button selected) doesn't dispatch events to view; instead, it runs performClick directly - no events on view, no onTouchesDown

Test plan

Pull request overview

This PR improves Android TalkBack behavior across RNGH “pressable”/button primitives by ensuring press state transitions and accessibility actions still work even when TalkBack bypasses normal touch-event delivery.

Changes:

• Adjust Pressable’s Android + screen reader flow to drive onPressIn from NATIVE_BEGIN (with optional LONG_PRESS_TOUCHES_DOWN) and provide a synthetic event payload when needed.
• Extend the Pressable state machine to support optional steps.
• Update Android button native code to better support long-press accessibility actions and to avoid activating native handlers when events are already passing through (isPressed case); also stop skipping events in NativeViewGestureHandler under TalkBack.

I've looked into the provided example and it seems that Legacy Pressable doesn't work. Maybe it is on my side, but could you double-check that? 😅

[m-bert]

Can't we just set isLongClickable and then use it?

Suggested change

	val hasLongPress = hasLongPressAccessibilityAction()
	setOnLongClickListener(if (hasLongPress) dummyLongClickListener else null)
	isLongClickable = hasLongPress
	isLongClickable = hasLongPressAccessibilityAction()
	setOnLongClickListener(if (isLongClickable) dummyLongClickListener else null)
