feat: Cherry-pick DH-20363: Pivot filter support #2602

[vbabich]

Added support for filtering on pivot columns (e.g., ColumnBy) that use negative column indices, and makes filter input positioning extensible for plugins.

Added two new methods to IrisGridMetricCalculator:
getFilterInputCoordinates: Returns positioning for the filter input field
getAdvancedFilterButtonCoordinates: Returns positioning for the advanced filter button
Both methods return null for negative indices by default, allowing plugins to override for custom column types

Added showAdvancedFilterButton prop to FilterInputField to hide the advanced filter button for columns that don't support advanced filters.
