[DC] Implement LargePayloadSupport for Digital Credentials

Implements ResultReceiver for large payloads in
DigitalCredentialsPresentationDelegate to avoid
TransactionTooLargeException when responses exceed Binder IPC limits.

This aligns with updates in Jetpack libraries (AOSP CL 3989977) where
large payloads are passed via file descriptors. Because Chrome bypasses
standard Jetpack UI launching, it must manually include the
ResultReceiver in the intent.

I also added a unit test to verify the behavior.
