Add percentage closer filtering to shadowmap sampling and a `shadow_filter_radius` property to lights to control it. Notes: * This adds PCF to `eevee_shadow_tracing_lib`, but not to `eevee_shadow_lib`, which is used by volumes (not required) and thickness. * PCF is computed based on the LOD0 size. This assumes that higher LODs are only used when the shadowmap resolution is actually good enough to match the render resolution.
