Jiří Polášek 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.
