Remove deprecated TabletLocator methods (#3320)

## Summary
Remove deprecated methods that use non-public TabletLocator class.

## Files Changed
- `BatchScannerSession.java` - Remove `setTabletLocator(TabletLocator)`
method (was a no-op)
- `PushdownFunction.java` - Remove constructor with TabletLocator
parameter

## Notes
These methods were deprecated in PR #3246 and are no longer functional
since TabletLocator usage was removed from BulkInputFormat.

Fixes #3319
Part of #2443
