Can not overwrite the `CheckBoxSize` or `CheckBoxGlyphSize` for CheckBoxSize

[SongOfYouth]

Describe the bug

Can not change the CheckGlyph size by overwritting the CheckBoxSize or CheckBoxGlyphSize resource, because they are assigned via StaticResource : https://github.com/microsoft/microsoft-ui-xaml/blob/589ced40542b9b4de2fddf0e58a1e3eecd164e2f/src/controls/dev/CommonStyles/CheckBox_themeresources.xaml#L602。

Steps to reproduce the bug

<CheckBox Content="CheckBox"
          MinWidth="8">
    <CheckBox.Resources>
        <x:Double x:Key="CheckBoxGlyphSize">8</x:Double>
        <x:Double x:Key="CheckBoxSize">8</x:Double>
    </CheckBox.Resources>
</CheckBox>
