Attachment: Bug 1704944 - Add SubSlice struct to picture cache instances.

This patch adds the SubSlice structure as a container of both
a tile grid and native surface within a picture cache instance.

There are no functional changes in this patch - it just adds the
new structure, and only ever creates a single sub-slice, which
all primitives are added to. The intent is to make follow up patches
easier to review, by introducing this non-functional change which
causes a lot of indentation changes in the diff.

In future, multiple sub-slices will be created for picture caches
that contain compositor surfaces.
