[E2E] Rename E2ETestIds to AccessibilityIdentifiers

[kyle-schellen]

What changes are you making?

Renames E2ETestIds to AccessibilityIdentifiers in the three sample apps, and moves it out of each sample's e2e/ folder into a sibling accessibility/ folder.

Follow-up to Mark's comment on #560:

Would love if we could drop E2ETestIds in favour of something more generic like AccessibilityIdentifiers since this is sample code that a merchant might use

The samples are reference code merchants read to learn Checkout Kit. They don't need to know we drive these apps with an E2E suite, so our test vocabulary shouldn't show up in the screens they're reading. AccessibilityIdentifiers is also just the more accurate name — these are applied via accessibilityIdentifier, testTag and testID.

The file moves out of e2e/ for the same reason: leaving it there would keep e2e in the import line of every screen.

No behaviour change. Every identifier value is byte-for-byte identical, so no Maestro flow, tag or matrix entry is affected.

Still in e2e/: the harness itself (E2EController, E2EControlLink, E2ESampleAppTarget, useE2ECartBootstrap). That code really is test infrastructure, and the label is what tells a merchant to skip the folder.

How to test

CI covers all three platforms.
