Config: add compile_get!feature/compile_get

It utilizes
[`Application.compile_env!`](https://github.com/elixir-lang/elixir/pull/9628)
to crash the application when compile-time configuration is attempted to
be set at runtime. If `Application.compile_env!` is not available it just falls back to
regular `Pleroma.Config.get``
