1382: Test Refactor r=syrusakbary a=syrusakbary # Description This PR is the continuation of #1380. It refactors our testing infrastructure based on various points: * There is no longer a "default compiler" on tests * Tests are automatically generated for: emscripten and wasi * It accelerates testing into multiple threads when possible (with the exception of the llvm backend) * It automatically detects the backends available in the host Summary of changes: * [x] Removed all extra logic for test creation in emscripten test generator * [x] Removed all extra logic for test creation in the wasi test generator * [x] Divided wasmer wast test in different files (under `tests/custom/`) * [x] Refactored trap asserts using the wast format * [x] Improved the build script by adding emscripten and wasi test generators (separated from build) * [x] Improved WASI errors to be Rust error types (by deriving from `thiserror::Error`) * [x] Fixed toolchain error creation * [x] Removed leaking of testing logic from generators into build * [x] Refactored import tests to be compatible with multiple backends * [x] Improved wasmer binary to work even when no backends are set (useful for testing without any backend available). * [x] Removed assumption that Cranelift will be the default in the `wasmer` binary * [x] Migrated middleware # Review - [x] Add a short description of the the change to the CHANGELOG.md file Co-authored-by: Syrus <me@syrusakbary.com> Co-authored-by: Syrus Akbary <me@syrusakbary.com>
