[Qt] Create ShadowBlur on demand.
https://bugs.webkit.org/show_bug.cgi?id=113506
Reviewed by Noam Rosenthal.
This patch creates ShadowBlur objects on demand instead of keeping a single one alive for
each GraphicsContext. This matches what other platforms does and fixes the problem with
an active shadowblur being affected by changing shadow settings on the GraphicsContext.
The method mustUseShadowBlur is moved from ShadowBlur to GraphcisContext, so that it can
be used to determine if a ShadowBlur object should even be generated.
