[FLINK-37552] Support switching between ForStKeyedStatebackend and ForStSyncKeyedStatebackend

[mayuehappy]

…rStSyncKeyedStatebackend

What is the purpose of the change

(For example: This pull request makes task deployment go through the blob server, rather than through RPC. That way we avoid re-transferring them on each deployment (during recovery).)

Support switching between ForStKeyedStatebackend and ForStSyncKeyedStatebackend

Brief change log

Convert the StateMetaInfo of ForStKeyeStatebackend and ForStSyncKeyeStatebackend into a unified format through the RegisteredStateMetaInfoUtils during recovery.

Verifying this change

(Please pick either of the following options)

This change is already covered by existing tests, such as (please describe tests).

ForStAsyncAndSyncCompatibilityTest#testForStTransFromAsyncToSync and ForStAsyncAndSyncCompatibilityTest#testForStTransFromSyncToAsync

This change added tests and can be verified as follows:

(example:)

• Added integration tests for end-to-end deployment with large payloads (100MB)
• Extended integration test for recovery after master (JobManager) failure
• Added test that validates that TaskInfo is transferred only once across recoveries
• Manually verified the change by running a 4 node cluster with 2 JobManagers and 4 TaskManagers, a stateful streaming program, and killing one JobManager and two TaskManagers during the execution, verifying that recovery happens correctly.

Does this pull request potentially affect one of the following parts:

Thanks for the PR! One overall question:

Could we transform snapshot to metainfo directly in recovery code path, instead of transform from two versions of metainfo?
