File system lookups are somewhat expensive, so cache the results to
avoid repetitive lookups. The default cache size of 500 is a rough
estimate based on that the default assets have 300+ images per scale
factor.
Caching image lookups gives an average of 20% performance improvement
in qmlbench:

Caching can be disabled by setting an environment variable:
QT_QUICK_CONTROLS_IMAGINE_CACHE=0
but this is not advertised in the docs for the time being. It is
there to help debugging, should anything go wrong with caching.

The output helps to debug image asset selection. For example:
qt.quick.controls.imagine: "button-background" () -> "path/to/button-background.9.png"
qt.quick.controls.imagine: "button-background" ("hovered") -> "path/to/button-background-hovered.9.png"

The Imagine style is based on image assets. The style comes with a
default set of images, but the images can be easily changed by
providing a directory with images using a predefined naming convention.
[ChangeLog][Controls] Added the Imagine style, which is based on
image assets that can be provided using a predefined naming convention.
