feat(MatDateRangeInput): export MAT_DATE_RANGE_INPUT_PARENT with DatePicker Module

[albahrawy]

Feature Description

I'm trying to extend MatDateRangeInput component and I wanna provide MAT_DATE_RANGE_INPUT_PARENT to use my extended class instead,
the issue here is the MAT_DATE_RANGE_INPUT_PARENT is not exported with DatePicker Module, is the any chance to export it so it wll be easy to use it.

Thanks

Use Case

import {MAT_DATE_RANGE_INPUT_PARENT , MatDateRangeInput} from '@angular/material/datepicker';
// MAT_DATE_RANGE_INPUT_PARENT is not exported from datepicker

@component({
providers: [
{ provide: MAT_DATE_RANGE_INPUT_PARENT , useExisting: CSDateRangeInput },
],
})
export class CSDateRangeInput extends MatDateRangeInput{}
