Cosmos: Promote Full Fidelity Change Feed (AllVersionsAndDeletes) API to GA

[ananth7592]

Promote Full Fidelity Change Feed (AllVersionsAndDeletes) APIs to GA

Removes @beta from FFCF / AllVersionsAndDeletes public APIs. The deprecated fullFidelity / createFullFidelityPolicy / createIncrementalPolicy / getFullFidelityRetentionDuration methods are intentionally kept for back-compat. ChangeFeedMode.FULL_FIDELITY enum is also kept (continuation token wire format).

Resolves #48959

• createAllVersionsAndDeletesPolicy(Duration retentionDuration) is now GA, but it still dereferences retentionDuration without a null check, leading to an unhelpful NullPointerException if callers pass null. Add an explicit null validation (e.g., Objects.requireNonNull) with a clear parameter name/message before the existing argument validation.

    public static ChangeFeedPolicy createAllVersionsAndDeletesPolicy(Duration retentionDuration) {

        if (retentionDuration.isNegative() ||
            retentionDuration.isZero() ||
            retentionDuration.getNano() != 0 ||
