Add IconPicker to New Tab Menu folders in SUI (#19591)

## Summary of the Pull Request
This PR pulls out the icon picker used in Profiles_Base.xaml to be its
own control. Then it's reused as a way to set an icon on folders in the
new tab menu.

As a part of pulling out the icon picker into its own control, some
minor code-health polish was added (i.e. lazy loading icon types and
built in icons).

The new tab menu didn't have a `NavigateToPageArgs`, so I took the
declaration from #19519 and moved it here. I chose to do that instead of
creating a `NavigateToNewTabMenuArgs` since that's more strict and it
would be removed as a part of #19519 anyways.

Aside from that, the PR is pretty straightforward.
