[SPARK-58851][SS] Add missing scaladoc for streaming progress parameters
### What changes were proposed in this pull request?
This PR adds missing scaladoc `param` documentation to the public
Structured Streaming progress classes in `sql/api`
(`org/apache/spark/sql/streaming/progress.scala`):
- `StreamingQueryProgress`: adds `param sink`.
- `SinkProgress`: adds `param metrics`.
- `StateOperatorProgress`: adds `param` tags for all of its constructor
parameters (`operatorName`, `numRowsTotal`, `numRowsUpdated`,
`allUpdatesTimeMs`, `numRowsRemoved`, `allRemovalsTimeMs`, `commitTimeMs`,
`memoryUsedBytes`, `numRowsDroppedByWatermark`, `numShufflePartitions`,
`numStateStoreInstances`, `customMetrics`).
This is a documentation-only change; no code is modified.
### Why are the changes needed?
These are public, `Evolving` API classes surfaced through the streaming
query listener and `StreamingQueryProgress`. Their scaladoc omitted several
`param` entries, so the generated API docs were incomplete for fields users
read when consuming progress events.
### Does this PR introduce _any_ user-facing change?
No. Documentation-only change.
### How was this patch tested?
No tests are required; the change adds scaladoc only. Each added `param`
name was verified to match a constructor parameter of its class, and each
description was checked against how the field is populated (`ProgressReporter`,
`statefulOperators`). Changed lines stay within 100 characters and introduce no
non-ASCII characters.
### Was this patch authored or co-authored using generative AI tooling?
Generated-by: Claude Code (Opus 4.8)
Closes #58096 from uros-b/apidoc-streaming-progress-params.
