Phase 18: HoodieAvroUtils Method Removal

[bvaradar]

Remove migrated methods from HoodieAvroUtils and consolidate remaining functionality.

Scope: org.apache.hudi.avro.HoodieAvroUtils

Changes: Remove methods that were migrated to HoodieSchemaUtils, consolidate remaining Avro-specific utilities, update documentation

Strategy: Method-by-method removal with validation, identify any remaining dependencies on old methods

Constraints: Keep essential record serialization methods, maintain timeline metadata compatibility

Files: HoodieAvroUtils.java, update all remaining callers

Will take this.

I am going to split the work here into stages so that it is easier to review. I'll go through the code by module, swapping out HoodieAvroUtils wherever possible. I will call out any classes that are left untouched.

If the modules are too small, i will merge it together with another module.

Do note that the changes might still touch multiple modules outside of the defined scope as these modules might be used by other modules as a dependency. As such, I will only resolve to fixing the compilation error. Any other code changes left out will be covered subsequently when i am doing a full sweep of that module.

P.S. LOL, i sound like i am prompt engineering, just wanted to call this out.
