Until now when a Component without a parent was passed to setOwner() the
ParentVisibilityChangedListener would not install any hooks to any
components, hence it would not be notified, when the owner was added
to a parent.

Regions marked as dirty by repaint calls are now queued up and
dispatched when the corresponding physical display device is
refreshed

This includes Carbon support

Also updates the drop shadower so that the DPI-awareness of the shadows
matches the DPI-awareness of the shadowed component.

This restores the functionality of JUCE_COREGRAPHICS_RENDER_WITH_MULTIPLE_PAINT_CALLS.
Using this preprocessor flag may avoid Core Graphics rendering much larger regions than
necessary, but the small regions that are rendered will likely be rendered slower.
Whether using this flag improves or degrades the performance of your rendering overall
will be specific to each application.

Previously enabling JUCE_COREGRAPHICS_RENDER_WITH_MULTIPLE_PAINT_CALLS was ineffective
from versions of macOS around 10.13, but enabling it didn't have any negative impact on
performance. Now enabling JUCE_COREGRAPHICS_RENDER_WITH_MULTIPLE_PAINT_CALLS may result
in slower rendering.

The helper function setComponentAsyncLayerBackedViewDisabled has been replaced
by a windowRequiresSynchronousCoreGraphicsRendering ComponentPeer style flag.

Fix improper use of non-atomic pointer validity to report state of background search thread state

This partially reverts f43784dc: "macOS:  Propagate focus loss message when resigning key window status and only grab focus if window can become the key window"

The change introduced in 92f350e617 led to
a regression in the MoveEndpointByUnit function. In this case, a
backward movement by a single character *should* move the endpoint as
long as it remains within the text range.

The issue addressed by the faulty commit is better fixed by
special-casing the 'character' unit case in the ExpandToEnclosingUnit
function.
