Android NamedSize.Header changed from 96 to 14

[beeradmoore]

Description of Change

This used to be a bug in Xamarin.Forms when running on Android that the font size for NamedSize.Header font was 96, this was later dropped to 14.

MAUI is using 96. This PR brings it back down to 14 to match incoming Xamarin.Forms users.

Fixes #7428

Do we use this on MAUI outiside Compatibility ?

Most probably not. I searched the docs and came up empty. I then used google site search and the only reference is in FontImage for xaml markup.

Size of type double, the size, in device-independent units, of the rendered font icon. The default value is 30. In addition, this property can be set to a named font size.

Document for Label even only says

FontSize, of type double, defines the font size.

EDIT:
Even the file for NamedSize marked it as obsolete. The only reason it doesn't show up in builds is because the warning is suppressed in multiple places.

There is no info on what we should be doing instead, I assume people should be defining styles and moving away from NamedSize (if we are using it, I am not) ?
