chore: make it possible to choose between static build or dynamic one

New feature `static_build` is added to Cargo.toml. By default dynamic
build is being used. build.rs is changed to respect it.

Use `cargo build --features static_build` to build static binary.

Previous attempt directly modified static-build cmake files which
is less convenient and doesnt allow us to support both build types
at the same time
