* implement component support
This updates Spin to use [the Component
Model](https://github.com/WebAssembly/component-model/tree/main/design/high-level)
natively instead of core Wasm modules (except for WAGI -- see below).
Core modules are still supported transparently via
[`spin-componentize`](https://github.com/fermyon/spin-componentize).
For now, the SDKs will continue to produce core modules (which the
developer can convert to components ahead of time via
`spin-componentize` if desired). Eventually, we'll want the SDKs to
target the Component Model directly as language toolchain support
matures. For the time being, though, we'll consider Component support
experimental.
WAGI is stuck on Preview 1 and modules because there's no reliable way
to wrap an arbitrary Preview 1 command in a component -- the Preview 1
-> 2 adapter only works with modules that either export
`canonical_abi_realloc` (e.g. native Spin apps) or use a recent
version of `wasi-sdk`, which contains patches to allow the adapter to
safely allocate memory via `memory.grow`.
In theory, someone could build a WAGI app using a new-enough version
of `wasi-sdk` and wrap it in a component using the adapter, but that
wouldn't add any value beyond leaving it as a module, and any
toolchain capable of natively producing components will be capable
enough to produce native Spin apps, so we probably won't ever support
WAGI components.
Note that I've moved the `spin-abi-conformance` project from this repo
to `spin-componentize` since it seems more relevant (and more likely
to be kept up-to-date) there. We can move it back later if that
changes.

* change `spin_core::Wasi` from a struct to an enum
This helps us detect and raise errors earlier if code tries to
initialize a Preview 1 store in a way only supported by Preview 2, or
vice versa. The duplication is still pretty ugly, but will go away
once the upstream WASI implementations are merged together.
