IGNITE-28528 Move the start request conversion out of the message

[anton-vinogradov]

StartRequestData marshalled itself: marshal(GridKernalContext) and unmarshal(GridKernalContext, UUID) picked the marshaller, resolved the peer deployment and ran the p2p hooks — all from inside the message. This moves that work to GridContinuousProcessor, the only place that has the sender id, the deployment and a thread where marshalling is allowed. The message keeps its fields and nothing else.

Nothing changes on the wire: the same eight @Order fields in the same order, the same marshaller, the same call order. What changes is where the marshaller is taken from — which is what IGNITE-28940 needs to switch it per transport.

Two details worth a look:

• The restored handler goes into the message right after it is read, before p2pUnmarshal. That order matters: p2pUnmarshal throws when the deployment is unavailable, and the caller still reads the handler afterwards to report the failure and stop the routine.
• nodeFilter and hnd became package-private, like the other fields of the class; the processor lives in the same package and reads them directly, as it already did with nodeFilterBytes and hndBytes.

Tested: CacheContinuousQueryFilterDeploymentFailedTest, GridCacheContinuousQueryNodesFilteringTest, CacheContinuousQueryDeploymentToClientTest, CacheContinuousQueryAsyncFilterListenerTest, CacheContinuousQueryEventBufferTest, GridEventConsumeSelfTest — green, checkstyle clean.

Superseded by #13440, which revises the marshalling instead of moving the conversion code around: the message now states the deployment it carries, and the class loader is resolved once, in the deployment manager.
