Table: Not able to provide custom Icons for column filter clear icon

[Rahulvr7]

Describe the bug

Not able to provide custom Icon for table column filter and clear filter icon. It's not mentioned in the documentation as well.
This is the template for the filter clear icon from the official source code in file table.ts:

<button #icon *ngIf="showClearButton && display === 'row'" [ngClass]="{ 'p-hidden-space': !hasRowFilter() }" type="button" class="p-column-filter-clear-button p-link" (click)="clearFilter()" [attr.aria-label]="clearButtonLabel">
                <FilterSlashIcon *ngIf="!clearIconTemplate" />
                <ng-template *ngTemplateOutlet="clearFilterIcon"></ng-template>
            </button>

Couldn't find any reference for clearIconTemplate nor clearFilterIcon through which users could provide custom icon template.
