Preliminary implementation of Google-style dialogs in ash::internal::DialogFrameView

This code is only compiled into Aura and only used if the "Google-style
dialogs" flag is specified (--aura-google-dialog-frames).

Remaining issues:

* Constrained windows are still broken -- see issue 109138.

* Title and body text should be #222, not black. This CL only affects the
  title, and currently leaves it at black to match the body text.

* The shadow and border stroke are not up to spec. Fixing this would require
  adding new image assets or rewriting the drawing code entirely.

* Some dialogs look pretty bad, such as the certificate viewer (which has
  a tab bar with the wrong look).

* The close button placement on medium- and small-sized dialogs may be wrong;
  there are no examples in the spec.

* There are sizing/positioning issues with various dialogs (for example, in
  Javascript popups the title bar is not always long enough to hold the title).
