alexcrichton opened PR #11885 from alexcrichton:refactor-resources to bytecodealliance:main:

This commit adds a new type wasmtime::component::ResourceDynamic to
the embedding API which internally is more-or-less the same as
Resource<T> but with different type information. This
ResourceDynamic specifically enables storing runtime information for
managing the type of the resource as opposed to Resource<T> which
requires static information.

The main goal of this type is to enable exposing resources in the C API
of Wasmtime. Currently there is no way to define different resource
types in the C API because the only option is Resource<T>. With this
type it will be possible to create distinct resource types in the C API
for embedders to use.

I'll note that to achieve this I felt it necessary to do some refactoring first. I've split up all of the refactorings as separate commits so this is likely easiest to look at commit-by-commit rather than all-at-once.
