* `-Clinker-plugin-lto` reduced the size of my contract
From:
Original wasm size: 68.6K, Optimized: 31.9K

To:
Original wasm size: 67.2K, Optimized: 31.0K

* Compiler will use `-Clinker-plugin-lto` if `lto` is enabled

* support offline flag for metadata generation

* cargo fmt

* cargo clippy

* fix tests

* Override verbosity to `quiet` when outputting JSON

* Update tests to include `OutputType` param

* Temporarily please Clippy

* Add some logging

This is gonna fail, but I want to see what the CI has to say.

* Mention this PR in the CHANGELOG

* Implement `Default` for a few build options

* Make `manifest_path` field public instead

Clippy was complaining about `dead_code` when building
in non-test mode, so I'm going with this instead.
