[Components] enable customized prefix

[yinonov]

apps integrated within other apps may result in multiple apps within the same custom elements registry. treating different versions of vivid components in an inconsistent manner.

• Explore the possibility for consumers to customize the custom elements prefix and enable their own scoping
  research the tradeoffs of customizing at build vs run-time.

• we need to support css selecting custom elements (e.g. accordion selecting accordion-item). as scss has no OOTB practice to communicate with JS, we'll need to find a way to intercept scss transpilation and interpolate an agreed block to a prefix refering selector.

• tokens should apply on enclosed scoping and not pierce in outside. that means adding a scss !default annotation to be able to change the variables applying on body selector
