Update wasmtime to 0.27 (#8913)

Browse Source 
* 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.
