While I was doing this I've additionally added a new`--preview2` argument to enable using the new experimentalimplementation of preview1 based on preview2 type/structs. This isoff-by-default but is expected to become the default in the future.Some notable features of this change are:* The preview1-implemented-with-preview2 module now sports `add_to_linker_{async,sync}` to replace the previous `add_to_linker` which always did async.* Some trait bounds in the preview1-implemented-with-preview2 module are simplified.* Some minor changes were made to `wiggle`'s macros to support a "block on" that isn't the default wiggle dummy executor (as now we actually do need Tokio)* Many options related to core wasm `Linker` configuration, such as `--default-values-unknown-imports`, are not implemented for components at this time. When used with components these options return an error.* Construction of WASI contexts has been refactored to pass around fewer arguments to avoid threading through lots of values for both preview1 and preview2.* Reading the input to the Wasmtime CLI has been updated to read the input in the `run` subcommand before handing it off to the `wasmtime` crate's API to enable the CLI to use the contents of what's loaded to determine what to do next.* Our generic `./ci/run-tests.sh` script has been updated to pass the `--features component-model` flag to ensure that this CLI support is tested during the normal test suite.* The CLI support for `wasi-nn` supports components as well as core wasm modules.
