Printing the `Schedule` is a useful debugging tool and general sanity
check. It is much more easy to interpret than the raw weights.
The printing relied on using `println` and hence was only available from
the native runtime. This is no longer available. This is why in this PR
we switch to using `log` which works from Wasm.
I made sure that the `WeightDebug` is only derived when
`runtime-benchmarks` is set so that we don't increase the size of the
binary.
Some other changes were necessary to make this actually work inside the
runtime. For example, I needed to remove `format!` and usage of floats.
Please note that this removed the decimal from the number because
truncating the fraction without using floats would not be easy and would
require custom code. I think the precision here is sufficient.
This is how the output looks like now:

Substrate
Substrate is a next-generation framework for blockchain innovation 🚀.
Getting Started
Head to docs.substrate.io and follow the installation
instructions. Then try out one of the tutorials. Refer to the Docker
instructions to quickly run Substrate, Substrate Node Template, Subkey, or to build a chain spec.
Community & Support
Join the highly active and supportive community on the Substrate Stack Exchange to ask questions about use and problems you run into using this software. Please do report bugs and issues here for anything you suspect requires action in the source.
Contributions & Code of Conduct
Please follow the contributions guidelines as outlined in docs/contributor/CONTRIBUTING.md.
In all communications and contributions, this project follows the Contributor Covenant Code of Conduct.
Security
The security policy and procedures can be found in

- Substrate Primitives (
sp-*), Frame (frame-*) and the pallets (pallets-*), binaries (/bin) and all other utilities are licensed under Apache 2.0. - Substrate Client (/client/*/sc-*) is licensed under GPL v3.0 with a classpath linking exception.
The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.
In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
