Code Review
This pull request updates the accessibility bridge to assign the kTextField role to all text fields, including read-only ones, and adds corresponding unit tests. Additionally, the Windows accessibility bridge is updated to dispatch kStateChanged events upon receiving ENABLED_CHANGED or READONLY_CHANGED events. Feedback suggests simplifying the OnAccessibilityEnabledChanged unit test by using the ExpectWinEventFromAXEvent helper function to reduce boilerplate.
Relands flutter#184501, which was reverted in flutter#186492 because mapping read-only text fields to Role::kTextField caused the macOS embedder to instantiate a FlutterTextPlatformNode for them, producing detached accessibility elements and test crashes. The underlying macOS issue is now fixed by flutter#190330 and flutter#190353. This relands the remaining bits of flutter#184501. In the common bits of the bridge, read-only text fields now map to `Role::kTextField`. In the Windows implementation `ENABLED_CHANGED` and `READONLY_CHANGED` are dispatched as MSAA `kStateChanged` events and `AXPlatformNodeWin` now raises the corresponding `UIA_IsEnabledPropertyId` change. Issue: flutter#184559
