[JSC] Drop translate phase in module loader
​https://bugs.webkit.org/show_bug.cgi?id=164861

Reviewed by Saam Barati.

Source/JavaScriptCore:

Originally, this "translate" phase was introduced to the module loader.
However, recent rework discussion[1] starts dropping this phase.
And this "translate" phase is meaningless in the browser side module loader
since this phase originally mimics the node.js's translation hook (like,
transpiling CoffeeScript source to JavaScript).

This "translate" phase is not necessary for the exposed HTML5
<script type="module"> tag right now. Once the module loader pipeline is
redefined and specified, we need to update the current loader anyway.
So dropping "translate" phase right now is OK.

This a bit simplifies the current module loader pipeline.
