IGNITE-28937 Register core messages uniformly: drop withSchema/withNoSchema

[anton-vinogradov]

Problem

After IGNITE-28929 the marshaller of a message is stated by @UseBinaryMarshaller, and CoreMessagesProvider#withSchema / #withNoSchema became the same code. They differ only by an assert that the annotation matches the chosen helper, so the same fact is stored twice and the assert only checks that the two copies agree. CalciteMessageFactory already uses the plain form register(factory, cls, id).

Separately, register threaded a Marshaller into the serializer and deployer lookups. Neither takes one: 0 of 197 generated serializers and 0 of 31 generated deployers declare a constructor with Marshaller, and the generators cannot emit one.

Solution

• 299 withSchema/withNoSchema calls replaced with register(factory, cls, msgIdx++), both helpers deleted;
• the marshaller now reaches only the generated marshaller companion — loadGenerated(cls, suffix) for the serializer and the deployer takes no marshaller and asserts the companion has a no-arg constructor, so a future change in the generator surfaces immediately.

Behaviour is unchanged. Note that until IGNITE-28940 removes the annotation altogether, a misplaced @UseBinaryMarshaller is silently ignored instead of tripping an assert.

Part of IGNITE-28935.

Verification

• message id map compared before and after by parsing both versions of the provider: 299 registrations, 0 differences in id -> class
• MessageProcessorTest — 39/39
• MessageFactoryMarshallerInitializationTest — 3/3
• DirectMarshallingMessagesTest — 1/1
• GridCacheAtomicNearEnabledFullApiSelfTest — 150/150
• full build with -Pcheckstyle — clean

Generated code is unchanged by construction: no message class is touched, only the provider and the factory base.
