[SPARK-59841][SQL] Align changelog state options and metadata reuse
### What changes were proposed in this pull request?
Add `TableCatalog.changelogStateOptionKeys()`, defaulting to
`tableStateOptionKeys()`, and pass only these declared options to the
catalog-level `loadChangelog` API. Keep all options on each relation for scan
planning. Reuse changelog metadata within an analysis or refresh pass by
`(catalog, identifier, ChangelogContext, changelog state options)`.
Use separate `V2TableReference` and `V2ChangelogReference` nodes under a
common `V2Reference` when re-resolving metadata. `ChangelogTable` captures the
post-processing requirements, validates option combinations at construction,
and checks compatibility when reloading an analyzed CDC plan. Plan comparison
relies on connector-provided `equals` and `hashCode`.
Preserve bounded CDC reads during refresh and DataFrame temporary-view
access. Refresh open-ended CDC reads through `loadChangelog`, retaining their
context and options. Transaction references continue to re-resolve through the
transaction catalog.
### Why are the changes needed?
[SPARK-59841](https://issues.apache.org/jira/browse/SPARK-59841):
`loadTable` uses declared state options, while `loadChangelog` receives all
options and does not share the same metadata-reuse semantics. Reads that differ
only in scan options should reuse CDC metadata; different ranges or state
options must remain separate.
Direct catalog-level CDC loading lets a connector read changes from
versions 1 through 10 when the latest version is 100 without Spark first
loading the current table snapshot.
### Does this PR introduce _any_ user-facing change?
Yes. `loadChangelog` now receives only options declared by
`changelogStateOptionKeys()`. Existing CDC connectors must declare any options
required during metadata loading and obtain Spark-parsed range and processing
parameters from `ChangelogContext`. Scan-only options remain available to
`Changelog.newScanBuilder`.
The new method defaults to the table state keys. An override supplies the
complete CDC state-key set, including any table keys the connector still needs.
The new API is marked `since 4.3.0`.
### How was this patch tested?
Passed 323 tests across the focused Catalyst, CDC, table-option, and
transaction suites below.
Focused reruns of `ChangelogTableSuite` (20 tests) and
`ChangelogResolutionSuite` (49 tests) also
passed. Java Checkstyle and Scala style checks for Catalyst and SQL
main/test sources passed,
along with whitespace and added-source ASCII checks.
The local Maven mirror rejects `at.yawk.lz4:lz4-java:1.12.0`, and public
Maven mirrors are unreachable from this environment. Local tests use the cached
1.11.3 artifact through the temporary SBT setting below; repository dependency
declarations are unchanged:
```text
set ThisBuild / dependencyOverrides += "at.yawk.lz4" % "lz4-java" % "1.11.3"
catalyst/testOnly *V2ReferenceSuite *ChangelogTableSuite
*CatalogV2UtilSuite *TableLookupCacheSuite
sql/testOnly *ChangelogResolutionSuite *ChangelogEndToEndSuite
*ResolveChangelogTable*Suite *DataSourceV2OptionSuite
*AppendDataTransactionSuite *StreamingTransactionSuite
```
