This commit updates the wasm-tools family of crates, notably pulling in
the refactorings and updates from bytecodealliance/wasm-tools#621 for
the latest iteration of the component model. This commit additionally
updates all support for the component model for these changes, notably:
* Many bits and pieces of type information was refactored. Many
`FooTypeIndex` namings are now `TypeFooIndex`. Additionally there is
now `TypeIndex` as well as `ComponentTypeIndex` for the two type index
spaces in a component.
* A number of new sections are now processed to handle the core and
component variants.
* Internal maps were split such as the `funcs` map into
`component_funcs` and `funcs` (same for `instances`).
* Canonical options are now processed individually instead of one bulk
`into` definition.
Overall this was not a major update to the internals of handling the
component model in Wasmtime. Instead this was mostly a surface-level
refactoring to make sure that everything lines up with the new binary
format for components.
* All text syntax used in tests was updated to the new syntax.
