VTK Dependency Audit

[svenevs]

External dependencies for the VTK builds need to be inspected. From https://github.com/RobotLocomotion/drake/issues/16502#issuecomment-1254102689

Confirmation that these are included in the drake setup scripts for macOS is the primary concern since we intend to distribute an archive rather than rely on brew formula dependencies. Beyond that, these may be good to prune out or make explicit dependencies of drake's setup/ scripts.

Updates from f2f today:

Most likely the only remaining work is to deal with these three libraries:

• libpng
• libtiff
• libjpeg

See TODOs in @vtk_internal:

https://github.com/RobotLocomotion/drake/blob/d718147dd37c110004848cb37f46cae8ab58eb99/tools/workspace/vtk_internal/settings.bzl#L550-L555

The goal is to make sure all three of those are properly vendored, ideally with drake_vendor_foo prefix not just vtkfoo.

Remember that libtiff got angry last time we tried this. Figure out why.
