* Reorganize wasi-misc-tests. Move wasi-misc-tests out of wasi-common, to break a dependency cycle; previously, wasmtime-* depended on wasi-common, but wasi-common dev-dependended on wasmtime-*. Now, wasi-common no longer dev-depends on wasmtime-*; instead, the tests are in their own crate which depends on wasi-common and on wasmtime-*. Also, rename wasi-misc-tests to wasi-tests for simplicity. This also removes the "wasm_tests" feature; it's replaced by the "test-programs" feature. * Update the CI script to use the new feature name. * Update the CI script to use the new feature name in one more place. * Change a `write!` to a `writeln!`.
