[html] provide rename for embedded JavaScript

[abdonrd]

• VSCode Version: v1.14.1
• OS Version: macOS Sierra v10.12.6
• Reproduces without extensions: Yes

Steps to Reproduce:

1. Create these two files:

my-custom-element.js

class MyCustomElement extends HTMLElement {
  static get is() {
    return 'my-custom-element';
  }
}

customElements.define(MyCustomElement.is, MyCustomElement);

my-custom-element.html

<script>
  class MyCustomElement extends HTMLElement {
    static get is() {
      return 'my-custom-element';
    }
  }

  customElements.define(MyCustomElement.is, MyCustomElement);
</script>

2. Try the Rename Refactoring with F2 in both files:

With the same code, the "Rename Refactoring" doesn't work in HTML language.

Rename is currently not provided inside embedded JavaScript. But you can use 'Change occurrences'

It could be great to have the same behavior inside script tags than we have in JS files. Like this one @abdonrd days and jsdocs comments per example.

Change occurrences doesn't work, it selects the character pattern in any context, so it ends up renaming a bunch of other things as well.

+1 hope this feature can be added, it will be very helpful!

We now have rename inside the script of the HTML file: #111644
However, we don't go across files. That's a general limitation of the HTML support which is only single file. #47331 is the main issue for cross file support.

I'm running Version: 1.56.2, but rename in <script> still doesn't work. Do I need to enable it somehow?
