test(rn): assert Android error code parity with errors.ts

[kieran-osgood-shopify]

What changes are you making?

errors.ts carried no documentation, so the API report listed every member as // (undocumented). Add a doc comment to each one, and mark webViewNotSupported as Android only — Android System WebView updates apart from the operating system and can lack WebMessageListener, and iOS reports no equivalent.

Add CheckoutErrorCodeParityTest. It enumerates CheckoutErrorCode from the published Android artifact and asserts each code appears in src/errors.ts. errors.ts is hand-maintained and silently coerces an unlisted native code to unknown, so nothing caught a missing member before.

Declare ../src/errors.ts as a Test task input in android/build.gradle. Without it Gradle reports testDebugUnitTest UP-TO-DATE and the test passes on stale state.

How to test

dev rn test android

Red first: delete a member from errors.ts and confirm the test names the missing code.

Stacked on #484.
