Change destruction order to avoid accessing deleted GL resources

This commit fixes a crash when a QQuickCanvas containing a
Text item is destroyed.

202127f860208c21145e05685bc54219e1655dbd in qtbase fixed a
resource leak with QOpenGLMultiGroupSharedResource; resources
were not cleaned up correctly when the associated GL context
(group) was destroyed.

This exposed a bug where QSGDefaultDistanceFieldGlyphCache
(used for Text items) relied on that leakage. In particular,
the glyph cache stores a pointer to a GL resource that it
doesn't own (m_textureData).

If the GL context is deleted and there are no other contexts
in the group, the group and its resources will be deleted.
Subsequently, if the glyph cache accesses the resource pointer
when the Text node is destroyed (via
QSGDefaultDistanceFieldGlyphCache::releaseGlyphs()), we crash.

The GL context is deleted when QQuickCanvasPlainRenderLoop is
destroyed. By moving the deletion of the render loop object to
the end of QQuickCanvas destructor, the canvas nodes get a
chance to clean up the resources they use _before_ the
resources are deleted.

Fix refill where zero-size items are involved

881091b5c0f1d2ead2b70e54f7ac2e4c17680b4e was incorrect since it meant
that any items following zero-sized delegates would not be deleted as
they scrolled up past the top of the view.

refill() should be deleting these items as well as any zero-sized items
before them.

Distance field glyph cache refactoring.

The distance field glyph cache is now an abstract class part of the
adaptation layer. It can be implemented to define the way the glyphs are
stored in graphics memory on a specific platform. The typical use case
is for having a cross-process glyph cache. To implement a custom glyph
cache, one has to override three pure virtual functions: requestGlyphs(),
storeGlyphs() and releaseGlyphs().

The default implementation works the same way as before the refactoring
(no cross-process cache).
