vala: Disable unity builds
Our approach to unity builds with vala is broken, you cannot unify the generated C files, as they contain duplicate symbols. We would need to instead combine the files while they are still in their vala form, then convert that to C and compile the unified C file. This does not fix the linked issue, as this removed the ability to do vala unity builds, but it does allow running vala with `--unity=on`. Related: #5280

+## Unity build with Vala disabled
+
+The approach that meson has used for Vala unity builds is incorrect, we
+combine the generated C files like we would any other C file. This is very
+fragile however, as the Vala compiler generates helper functions and macros
+which work fine when each file is a separate translation unit, but fail when
+they are combined.
