IgcGrid should expose a way to mask the columns and custom filter editors

An example that demonstrates this can be found here: https://www.infragistics.com/products/ignite-ui-web-components/web-components/components/grids/grid/column-types. Open the "Order Full Date" column's options menu and click Date Filter => Equals to open the custom filter dialog. Note the mask on the editor.

The above-mentioned mask will match what the grid applies in edit mode for that column, but there does not appear to be a way to configure this aside from defining an inline template editor - it currently appears to be completely based on the data-type property of the column at the moment and the custom filter dialog will not take the contents of the inline template editor either.

If the column happens to not be editable, this provides a disconnect between what the user potentially sees in the custom filter dialog and the format of the column as they would not be able to see the mask when in edit mode. There should be a way to configure this.
