feat(material/chips): add hideMultipleSelectionIndicator in mat-chip-listbox

### Feature Description

Currently there is an input `hideSingleSelectionIndicator` in ``, but if we set `multiple="true"` there is no option to hide all of them. So we need a boolean input `hideMultipleSelectionIndicator` as we have in ``

### Use Case

We want to use a multiple chip listbox indicating selected multi options without the indicator

Start by locating the mat-chip-listbox implementation and its existing hideSingleSelectionIndicator input, then compare the corresponding hideMultipleSelectionIndicator behavior in mat-button-toggle-group. Add the multiple-selection option and verify that selected chips can hide their indicators while single-selection behavior remains unchanged.
