Respect bounds and size constraints when modifying launch params for dw

Ensure the `DesktopModeLaunchParamsModifier` does not override any
bounds set in the activities options and respect any size contraints
set through the layout.

Layout contraints can include:
- width/ height
- fraction width/ height
- gravity

Any bounds set must also fall within the default bounds (the display
area bounds). In the event the bounds fall outside this are, the
default bounds will be used.
