Snooze/dismiss support in toast button builders

[andrewleader]

Fixes #3614

The toast button builders we added in 7.0 so far didn't support snooze/dismiss activation, it makes sense to have a single way of constructing a button regardless of the activation type.

Additionally, this helps us converge on using Uri types for images rather than string as mentioned in issue #3614.

What is the current behavior?

Had to use a separate button type previously...

new ToastContentBuilder()
                
    .AddButton(new ToastButton()
        .SetContent("Delete")
        .SetImageUri(new Uri("delete.png"))
        .AddArgument("action", "delete")
        .SetBackgroundActivation()

    .AddButton(new ToastButtonDismiss()
        {
            ImageUri = "dismiss.png"
        });

What is the new behavior?

Can use the same button builder, and the image consistently uses Uri type.

new ToastContentBuilder()
                
    .AddButton(new ToastButton()
        .SetContent("Delete")
        .SetImageUri(new Uri("delete.png"))
        .AddArgument("action", "delete")
        .SetBackgroundActivation()

    .AddButton(new ToastButton()
        .SetImageUri(new Uri("dismiss.png"))
        .SetDismissActivation());

Hi @andrewleader, Thanks for all the work and for submitting the PR.

For testing purposes, whenever I am trying to run the sample app it keeps breaking for me the moment I select the Toast sample app and constantly encountering the following error. Wondering if you are able to repro this as well?

[andrewleader]

Whoops, fixing!

[andrewleader]

Alright fixed!
