Reland: Ash: Allow resize along 1 pixel edge inside window content
The mocks call for resize handles to function along a single pixel edge inside the window, overlapping the web content. Refactored aura::Window::set_hit_test_bounds_inset() into SetHitTestBoundsOverride() to make hover/click events along that border pass through to the non-client area of the window frames. This also allows windows to be resized when they are flush against the top/left/right edges of the screen.

TEST=aura_shell_unittests ShelfLayoutManager, manually resize window from left/right/bottom/top edges
