[ManagedLedger] Compress managed ledger info (#11490)
* compress managed ledger info * 1. Move the `ManagedLedgerInfoMetadata` to `MLDataFormats.proto`. 2. Add configuration managedLedgerInfoCompressionType to control ManagedLedgerInfo compression type. * use ByteBuf wrap bytes array, release ByteBuf if needed. * make the compressionType as a final field * fix comment * 1. throw exception if using a invalid compression type. 2. change compression magic number. 3. add a unit test to verify compression could work well. * change compression magic number. * fix test
