Fix Android Pressable TalkBack activation

[sorinc03]

Description

Fixes #3899. Root-cause note: #3899 (comment)

TalkBack's double-tap activation dispatches an Android accessibility click/action to the native view rather than the touch stream consumed by Pressable's gesture state machine. That means the FINALIZE -> handlePressOut path that calls onPress is never reached. PR #4017 helped with touch-event ordering, but it does not cover this accessibility-action channel.

This brings Pressable and LegacyPressable to parity with the existing touchables by:

• adding default Android accessibility actions for activate and longpress when the corresponding press handlers exist;
• routing activate through the existing onPressIn -> onPressOut -> onPress lifecycle using synthetic layout-local press events;
• routing longpress to onLongPress;
• preserving user-provided accessibility actions and forwarding onAccessibilityAction;
• avoiding duplicate onPress calls for apps that already supplied their own user-handled activate action workaround;
• sharing the Android accessibility-action wiring between the v3 and legacy implementations.

Test plan

• yarn test Pressable.accessibility.test.tsx
• yarn test
• yarn ts-check
• yarn lint:js (passes with existing repo warnings only)
• git diff --check

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Adds Android-specific accessibility actions to both v3 Pressable and legacy Pressable, routing activate/longpress accessibility actions into the existing press lifecycle, and introduces helpers + tests to validate the behavior.

Changes:

• Add default accessibilityActions (activate/longpress) on Android when press handlers are present, without overriding user-provided actions.
• Handle onAccessibilityAction by triggering press lifecycle / long-press callbacks when the user hasn’t explicitly handled the action.
• Add shared utilities for default action generation + synthetic press events, plus new Jest tests for both implementations.
