VTK: better optional dependency detection
This update primarily brings in optional dependency check fixes in order
to better support external VTK (not official, but vcpkg is attempting
it). This backports MRs !6766 (merged) and !6770 (merged) which deal with optional
dependency fixes.
Also brings in various bugfixes from VTK as well.
