Prep work for serializing display lists across the IPC boundary. Replace Gfx::Filter's Skia-specific backing with a portable Variant-based representation, add serialize_filter/deserialize_filter, and store filter data inline in ApplyEffects/ApplyBackdropFilter command payloads instead of in DisplayListResourceStorage. FilterResourceId is removed along with the per-storage filter map.
