enable single commit summary via supportedFeatures in routerlicious

[pragya91]

Enable single-commit summaries via summarizeProtocolTree policy flag in IDocumentServicePolicies - which for routerlicious will be set when enable_single_commit_summary flag is provided in the supportedFeatures property bag in IConnected. This change is particularly aimed at enabling slow rollouts of FRS clients on the single-commit summary flow.

1. updated routerlicious-driver's documentService to check the supported features and set the summarizeProtocolTree driver policy. Container uses this flag to check whether or not the protocol tree should be added to the summary before sending the summary.
2. Updated containerStorageAdapter to always initialize ProtocolTreeStorageService.
3. ProtocolTreeStorageService uses a callback to check whether it should upload protocoltree with summary or not. This is done to ensure we are using the most updated value of driver policy which will be set correctly only when the delta connection is established.
4. Renamed forceEnableSummarizeProtocolTree to shouldSummarizeProtocolTree.
