CmdPal: Cleanup warnings, part 1 (#42584)

## Summary of the Pull Request

This PR fixes several warnings in the Command Palette projects.


- _MSB4011_: `"Sdk.props" cannot be imported again. It was already
imported ...`
  - Removed the `Sdk` attribute from `CoreCommonProps.props`.

- _CsWinRT1028_ – “Class should be marked partial” on
*CsWin32*-generated classes.
- Since these classes cannot be made partial, a suppression attribute
has been added.
  - The `LocalKeyboardListener` type has been marked as partial.

- _Resource.resx_ – some strings had empty values.  
  - Updated the missing content.

- _WMC1506_ – *OneWay* bindings require at least one step to support
change notifications.
- In `SettingsWindow.xaml`, the breadcrumb binding was changed from
*OneWay* to *OneTime*, as `Crumb` does not support change notifications.

- _WMC0001_ – Unknown type in XML namespace
- In `SettingsWindow.xaml`, `FontWeight` was qualified with the CLR
namespace `Windows.UI.Text`.
