Removes control type from NavBar's accessible names

[AmadeusW]

This fixes #18443 - Accessible name should not contain the type of the control.

Narrator automatically adds the control type, which means that with this fix in place, hitting Ctrl+F2 as described in #18443 will make Narrator say "Projects, WpfApp1, ComboBox"

Had no idea the interface delegated the automation properties.

@Pilchie: I think we updated the regexes that you have to reference @dotnet-bot now.

Tagging @ManishJayaswal for approval, since we forgot to hit merge on this before :-/

Approving without ask mode for accessibility fixes.
