This allows targets that don't link with a vala target to rely on the header generation.
Same as the previous, but for VAPI

I'm no meson maintainer, but I provided the required steps in elementary/granite#873 (comment), as it depends on this PR to work. I can confirm that it builds successfully and works without any problems, so you have my approval on the testing side of things.

When compiling Vala we generating 2-3 files as side effects of the compilation. A C compatible header, a VAPI header, and possibly a GIR file. Currently, there is no good way to generate a dependency on those files.
With this PR that changes, as a build target has
vala_header()vala_vapi()andvala_gir()method, each returning a File object pointing to their respective generated target. Calling these methods on a target that doesn't use Vala, or that doesn't generate a GIR file, will result in an error.
