Deno.emit() with check: false does not support module compiler option

[kitsonk]

The following code does not work as expected:

const { diagnostics, files, ignoredOptions, stats } = await Deno.emit(
  "/foo.ts",
  {
    check: false,
    compilerOptions: {
      module: "amd",
      sourceMap: false,
    },
    sources: { "/foo.ts": `export const foo = "foo";` },
  },
);

It simply outputs and ESM module. Where as if check is true it will output an AMD module.

If swc doesn't support AMD, CommonJS, System and UMD we should throw here with invalid options, if it does, we should implement the functionality.

Here is a specific test case that can be added to cli/tests/compiler_api_test.ts the demonstrates the issue. It should pass:

Deno.test({
  name: "Deno.emit() - no check - supports other module formats",
  async fn() {
    const { diagnostics, files, ignoredOptions, stats } = await Deno.emit(
      "/foo.ts",
      {
        check: false,
        compilerOptions: {
          module: "amd",
          sourceMap: false,
        },
        sources: { "/foo.ts": `export const foo = "foo";` },
      },
    );
    assertEquals(diagnostics.length, 0);
    assert(!ignoredOptions);
    assertEquals(stats.length, 12);
    const keys = Object.keys(files);
    assertEquals(keys.length, 1);
    const key = keys[0];
    assert(key.endsWith("/foo.ts.js"));
    assert(files[key].startsWith("define("));
  },
});
