adoptedStyleSheets polyfill

[foxeyes]

adoptedStyleSheets - is a very important and useful API implemented in all modern browsers:
https://developer.mozilla.org/en-US/docs/Web/API/Document/adoptedStyleSheets

It's good to switch on it for the Symbiote CSS workflow. But, we should support older browsers, so we need to consider creation of polyfill, that can work synchronously and not violate CSP settings in common.

The idea is to try approach with base64 encoded src for the inline style element, added to the each root.

What we should chek:

• Inner CSS @imports
• Speed overhead
• Behavior in case of component inheritance
• Behavior for the multiple style sheets in array
