[ShadowDOM] Replace createDom and createShadow function in LayoutTests/fast/dom/shadow/create-dom.js with more flexible one

• Component: DOM
• Status: RESOLVED FIXED

[Hayato Ito]

This is a separated, but independent, patch from https://bugs.webkit.org/show_bug.cgi?id=79197.

We need to improve createDom and createShadow function defined in LayoutTests/fast/dom/shadow/create-dom.js because:
  - createShadow is confusing name. It actually creates ShadowHost and ShadowRoot at the same time.
  - createDom should be named createDOM since WebKit doesn't use CamelCase for abbreviation.
  - It might be better that we can create lightChildren and ShadowRoot for an element at the same time in one expression. This is impossible in the current implementation.

This typo is making the tests fail on platforms that don't have SHADOW_ROOT enabled. Shouldn't have "new".

[Hayato Ito]

Ops. My bad. I should have tested this patch on platforms which don't have SHADOW_ROOT enabled.
