Attachment: Bug 1704687 - Refactor visibility flags and how pass-through picture visibility is handled.

Move PrimitiveVisibility flags inside the Coarse / Detailed enums
which will be important once these enum fields also include info
about the z-slice that a primitive exists on in a picture cache.

Add a PassThrough variant of the enum for pictures that are
containers without a surface. These pictures don't have a z-slice
since they don't have bounds, so it's simpler to handle them this
way for now (although we aim to remove them completely in future).

This meant moving how we currently handle the 3d render context
container picture during batching. This part is still quite untidy
but we aim to refactor it further in future.
