* 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. * Filter regalloc logging

License
- 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.
