Use `buildprefix` in a few more places `installcheck` doesn't yet work, but the rest of the build can now happen mostly inside a separate build directory. Progress on #9342 Co-authored-by: Valentin Gagarin <valentin.gagarin@tweag.io>

Use positive source filtering for the standalone functional tests job Additionally this skipping of the building is reimplemented to be a bit more robust and use the same idioms as the functionality for skipping the tests. In particular, it will now work even if the source files exist, so we can do this during development too.

Add ./configure --disable-tests option Building without tests is useful for bootstrapping with a smaller footprint or running the tests in a separate derivation. Otherwise, we do compile and run them. This isn't fine grained as to allow picking `check` but not `installcheck` or vice versa, but it's good enough for now. I've tried to use Nixpkgs' `checkInputs`, but those inputs weren't discovered properly by the configure script. We can emulate its behavior very well though.

Move tests to separate directories, and document Today, with the tests inside a `tests` intermingled with the corresponding library's source code, we have a few problems: - We have to be careful that wildcards don't end up with tests being built as part of Nix proper, or test headers being installed as part of Nix proper. - Tests in libraries but not executables is not right: - It means each executable runs the previous unit tests again, because it needs the libraries. - It doesn't work right on Windows, which doesn't want you to load a DLL just for the side global variable . It could be made to work with the dlopen equivalent, but that's gross! This reorg solves these problems. There is a remaining problem which is that sibbling headers (like `hash.hh` the test header vs `hash.hh` the main `libnixutil` header) end up shadowing each other. This PR doesn't solve that. That is left as future work for a future PR. Co-authored-by: Valentin Gagarin <valentin.gagarin@tweag.io>

Put functional tests in `tests/functional` I think it is bad for these reasons when `tests/` contains a mix of functional and integration tests - Concepts is harder to understand, the documentation makes a good unit vs functional vs integration distinction, but when the integration tests are just two subdirs within `tests/` this is not clear. - Source filtering in the `flake.nix` is more complex. We need to filter out some of the dirs from `tests/`, rather than simply pick the dirs we want and take all of them. This is a good sign the structure of what we are trying to do is not matching the structure of the files. With this change we have a clean: ```shell-session $ git show 'HEAD:tests' tree HEAD:tests functional/ installer/ nixos/ ```

enable LTO in optimized builds gives 2-5% performance improvement across a board of tests. LTO is broken when using clang; some libs link fine while others crash the linker with a segfault in the llvm linker plugin. 🙁

Including `config.h` also needs `$(buildprefix)` Per the instruction in the manual, we want to run configure in a different directory so that we can configure + build for multiple platforms. That means `config.h` will be in the build directory. This is just like `Makefile.config`, which already is used with `$(buildprefix)`.
