[TSLO] Update app modal dialog layout to avoid drawing in app header
area

This CL passes the InsetObserver to the ModalDialogManager instance
maintained by ChromeActivity to access the activity's raw system bar
insets when they are applied, to determine the minimum horizontal and
vertical margins to use relative to the window to avoid drawing into any
insets' regions. Note that the insets will be retrieved from the
activity window because the dialog window currently does not return the
expected system bar insets.

These margins will be used when the view is measured to determine
the correct size. This custom measurement will be done only for normal
(ie. non-fullscreen) dialogs.

The CL also accounts for new layout constraints as follows:
- Dialog maintains 16dp from the window edges.
- Dialog can be a maximum of 600dp (requires further follow-up tracked
in b/359976267).

The above changes are guarded behind ModalDialogLayoutWithSystemInsets.
