fix(core): module execution with top level await (#7672)

This commit fixes implementation of top level await in "deno_core".

Previously promise returned from module execution was ignored causing to execute
modules out-of-order.

With this commit promise returned from module execution is stored on "JsRuntime"
and event loop is polled until the promise resolves.
