[Feature] Ensure all controls have style names

Follow-on from microsoft/microsoft-ui-xaml#3735

Describe the problem this feature would solve

Over time in the toolkit we've been better at adopting better practices around making our styles. We should ensure that we go back and retroactively apply these to other older controls. 7.0 would be a good time to do this...

Describe the solution

Update Styles of controls to ensure that the base style is named and available. (though we may have another issue where these aren't getting exposed to the application level, see: #3556 (comment))

We also generally split out the ControlTemplate as well:

<Style TargetType="ControlName" BasedOn="DefaultControlNameStyle"/>

<Style x:Key="DefaultControlNameStyle" TargetType="ControlName">
    ...
    <Setter Property="Template" Value="{StaticResource DefaultControlTemplate}" />
</Style>

<ControlTemplate x:Key="DefaultControlTemplate" ...

Realizing that our DefaultColorPickerStyle is going to conflict with the System/WinUI one... we may want to rename it? DefaultToolkitColorPickerStyle?
