be90b587da CmdPal: Update Extension SDK classes to raise property change notifications only on change (#44547) 
## Summary of the Pull Request

This PR introduces a new method  
`bool SetProperty<T>(ref T field, T value, [CallerMemberName] string?
propertyName = null)`
on `BaseObservable`.

The method updates the backing field only when the new value differs
from the current one and raises property change notifications only in
that case.

#### Summary

- Adds `SetProperty<T>` to `BaseObservable` to guard property change
notifications behind an actual value change.
- SDK API is not affected.
- Prevents unnecessary notifications from leaving the extension
boundary.
- Reduces redundant updates and saves a few round-trips between COM
objects and view models.
- Improves overall efficiency without changing observable behavior for
consumers.

1887c22e87 CmdPal: Did someone say grid pages? (#40832) 
Closes #38269

Still working on this one, but essentially allows a list page to become
a grid page by specifying a `GridProperties` property like so:

```C#
public AllAppsPage()
{
    PlaceholderText = Resources.search_installed_apps_placeholder;
    GridProperties = new MediumGridLayout();
}
```

> This is a very early version and very subject to change. Much to
clean, but feedback & suggestions are welcome.
