Add minimal viewer build with Bazel.
This doesn't yet support all the slide types, but does allow us
to have a GM slide (with one gm for now).
I enforced IWYU on tools/viewer/ and gm/ to help resolve all
deps. How we handle command line flags is a bit unfortunate
(as a filegroup and not a cc_library), but I think that's
pretty tough to untangle for now.
We can add more slide types and gms as we see fit in future
CLs.
