Find the build directory from kbuild.toml

[radumereuta]

Projects using the kbuild system store the kompiled directory in something like this:
/Users/user/.kbuild/mir-semantics/49061f8/target/v5.6.88-0-g4c09d86ed2/llvm
klsp should query kbuild and find that location.

@tothtamas28 can you explain how to do that?

[tothtamas28]

Command kbuild which <target> should give that output.

If the definition hasn't been built yet, kbuild still returns the path, but it's going to be empty.
