* remove fetch_source_file_and_maybe_compile_async and replace it with State.fetch_compiled_module * remove SourceFile.js_source() * introduce CompiledModule which is basically the same as deno::SourceInfo and represents arbitrary file that has been compiled to JS module * introduce //cli/compilers module containing all compilers * introduce JsCompiler which is a no-op compiler - output is the same as input, no compilation takes place - it is used for MediaType::JavaScript and MediaType::Unknown * introduce JsonCompiler that wraps JSON in default export * support JS-to-JS compilation using checkJs
