LibWasm+Meta: Add test-wasm and optionally test the conformance tests
This only tests "can it be parsed", but the goal of this commit is to provide a test framework that can be built upon :) The conformance tests are downloaded, compiled* and installed only if the INCLUDE_WASM_SPEC_TESTS cmake option is enabled. (*) Since we do not yet have a wast parser, the compilation is delegated to an external tool from binaryen, `wasm-as`, which is required for the test suite download/install to succeed. This *does* run the tests in CI, but it currently does not include the spec conformance tests.
