[core] Add catalog name to Catalog and Table fullName

[Zouxxyy]

Purpose

Add catalog name to Table.fullName() so it returns catalog.database.table format. This helps users identify which catalog a table belongs to in UI and logs, making it easier to diagnose issues in multi-catalog environments.

• Added Catalog.name(), propagated via CatalogContext → CatalogEnvironment → AbstractFileStoreTable.fullName()
• Spark/Flink entry points pass catalog name into CatalogContext

Tests

DescribeTableTestBase, DDLWithHiveCatalogTestBase, V2WriteRequireDistributionTest

API and Format

• Catalog interface: added @Nullable String name()
• Table.fullName() may now return 3-part name
• CatalogEnvironment serialVersionUID bumped to 3

Documentation

No.

Pull request overview

Adds catalog name propagation so Table.fullName() can include the catalog prefix (catalog.database.table), improving clarity in multi-catalog logs/UI while keeping some callers compatible.

Changes:

• Introduce Catalog.name() and propagate catalog name through CatalogContext → CatalogEnvironment → AbstractFileStoreTable.fullName().
• Update Spark/Flink catalog creation paths to pass catalog name into CatalogContext.
• Adjust identifier parsing and multiple tests to reflect/handle the new 3-part naming.

I think this is a bit of a big change. It's not compatible and some systems already rely on it. Can we just modify the Spark side and pass the catalogName?
