[improve][broker] Supplement schema ledger if schema ledger is lost

[Denovo1998]

Fixes #20414

Master Issue: #https://github.com/apache/pulsar/issues/20414

Motivation

https://github.com/apache/pulsar/issues/17221 describes an environment when multiple bookie copies are corrupted, or a Ledger has been deleted. The loss of schema ledger results in new producers and consumers not even being created and working properly.

So we need a solution that does not just skip the schema with the missing ledger, but actually supplements the broken schema ledger.

Modifications

Add a new method tryCompleteTheLostSchema() in SchemaStorage and SchemaRegistry

CompletableFuture<Long> tryCompleteTheLostSchemaLedger(String key, SchemaVersion version, SchemaData schema);

1. get schemalocator from metastore
2. Create a new ledger. And write SchemaStorageFormat.SchemaEntry built with schemaData and schemaVersion.
3. update schemalocator to metastore(new ledger id)

@poorbarcode @congbobo184 @codelipenghui SchemaData and SchemaVersion has moved to the org.apache.pulsar.broker.service.AbstractTopic, rather than save in each producer and consumer. Check out the solution in issue #20414. Is this way okay now?

Waiting to discuss whether this plan is feasible. I will send an email to discuss it later.

In the alternative, the implementation is updated. Needs to be discussed.
