fix(igxGrid): Re-calculate column auto-sizes on data change. (#12324)
* fix(igxGrid): Re-calculate column auto-sizes on data change. * chore(*): Remove wrong import. * chore(*): Add test. * chore(*): Due to performance concerns limit autosizing only on the initial data load. Expose public api in case auto-sizes need to be recalculated. * chore(*): Wait for zone stable before mesuring the columns. * chore(*): Add note in changelog. * chore(*): Move changelog note under 15.0.1 Co-authored-by: MKirova <MKirova@DEV-MKIROVA> Co-authored-by: Zdravko Kolev <[email protected]> Co-authored-by: Martin Dragnev <[email protected]> Co-authored-by: Deyan Kamburov <[email protected]> Co-authored-by: Stamen Stoychev <[email protected]>

## 15.0.1
76

7+
- `IgxGrid`
8+
- Added new auto-sizing API `recalculateAutoSizes` that recalculates widths of columns that have size set to `auto`. Can be used in scenarios where you want to auto-size the columns again post initialization.
89
- `igxPivotGrid`
910
- Adding `aggregatorName` for pivot value configuration as an alternative to setting `aggregator` function. If both are set `aggregatorName` takes precedent. If none are set an error is thrown.
