Make HardwareLayer internal. It doesn't provide any API now, and when it does - we can provide it in SkiaLayer.

Added API to get the current SkiaLayer graphics API.

Some fixes after metal

We don't need them anymore, because `paint` will be called every time we change size and init layer.

It is because we changed java.awt.Canvas to javax.swing.JPanel

Metal API prototype.

Fix crash when we close the window immediately after its start

Schedule redraw on resize and initialization

We probably shouldn't perform frame rendering in init/setBounds.
Because in onRender we can call window.setBounds.
It will cause drawing onRender inside another onRender.

After the fix there is no increase in artifacts on start or resize.

"True" fix would be to call "repaint" instead of manual scheduling redrawing with "invokeLater", because paint events have higher priority than usual events.

But "repaint" doesn't work with Canvas. It is only works with Swing components.
We can extend JLayeredPane instead of HardwareLayer (and just add HardwareLayer to JLayeredPane).
But there are too much changes.

Anyway, system draws Window independently of AWT, so we probably can't get rid of artifacts if we use only AWT.

DirectX rendering implementation.
