REGRESSION (303819@main): Child with filter:blur() ignores border radius
overflow clipping

Reviewed by Said Abou-Hallawa.
When using the TransparencyLayerContextSwitcher path for filters, we need to be
able
to supply a complex clip for items clipped by border-radius on ancestors; this
requires running the code in `applyAncestorClippingForBorderRadius()` after
saving the graphics state, before starting the transparency layer, so factor
the code to allow this by passing a function to GraphicsContextSwitcher.
