CmdPal: Fix FiltersViewModel binding (#42467)

## Summary of the Pull Request

This PR resolves crashes on pages with filters, such as Windows Terminal
profiles or Windows Services, when compiled with trimming/AOT.

It removes runtime binding from the FiltersDropDown control, effectively
preventing crashes caused by trimming/AOT dropping binding metadata for
FilterItemViewModel.
