build: replace lib-vt step with -Demit-lib-vt option

Remove the dedicated `zig build lib-vt` step and replace it with a
`-Demit-lib-vt` build option. This fixes two problems:

1. We can default XCFramework, app, etc. steps to false if emit-lib-vt
   is true, so that the lib-vt build doesn't pull in unrelated
   artifacts. **Most importantly, lib-vt alone can be build without
   full Xcode installations.**

2. We can build lib-vt as part of a bundle with other artifacts if we
   really want.
