fix: aspect ratio when max width/height is set (#31955)

* fix: fix aspect ratio when max width/height is set

Add the native frame border size to the minimum and maximum size if
the view reports its size as the client size. It allows to enlarge
window to proper values when aspect ratio and max width/height are
set. It also fixes DCHECK which was triggered when user tried to
enlarge window above dimensions set during creation of the
BrowserWindow.

* chore: update patches
