Sergei Shulepov 7a284fcf1d Update wasmtime to 0.27 (#8913)
* Update wasmtime to 0.27

A couple of notes:

- Now we are fair about unsafeness of runtime creation via an compiled artifact.
  This change was prompted by the change in wasmtime which made
  `deserialize` rightfully unsafe. Now `CodeSupplyMode` was hidden and
  the `create_runtime` now takes the blob again and there is now a new
  fn for creating a runtime with a compiled artifact.
- This is a big change for wasmtime. They switched to the modern backend
  for code generation. While this can bring performance improvements, it
  can also introduce some problems. In fact, 0.27 fixed a serious issue
  that could lead to sandbox escape. Hence we need a proper burn in.

This would require a change to PVF validation host as well.

Contributions & Code of Conduct

Please follow the contributions guidelines as outlined in docs/CONTRIBUTING.adoc. In all communications and contributions, this project follows the Contributor Covenant Code of Conduct.

Security

The security policy and procedures can be found in docs/SECURITY.md.

License

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.
