Draft: meson: use cargo method

@dbaker This is an experiment that requires Meson master. I'm curious if we could get ride of all handwritten crates meson.build.

It fails to build for me because of bindgen, I think that's unrelated to Meson:

panicked at 'Unable to generate bindings: ClangDiagnostic("/usr/include/limits.h:124:16: fatal error: 'limits.h' file not found\n")', main.rs:52:36
