Automated Commit: Committing new LKGM version 4771.0.0 for chromeos.

Disable UI controls for maximize and fullscreen if an app window is constrained. (Mac)

This prevents an app window from being maximized or fullscreened by the
user if it has a maximum width or height, or if it is not resizable. Maximize
or fullscreen via the window API is still allowed.

Also, a window is not resizable if it's min and max sizes are specified
and equal.
