Compatibility fix for Polymer 2

Polymer 2 uses shadow dom. Before the fix all styles were loaded as a
document-level styles. To load styles inside correct element this fix
logically separates plugin in 2 parts: gr-editor and codemirror-element.
The codemirror-element is a wrapper for codemirror and it incapsulates all
styles and scripts inside the element. gr-editor connects codemirror-element
with gerrit - it dynamically loads codemirror-element, set correct
options and adds event listeners.
Also, codemirror doesn't work with shadydom correctly. Because of it,
there 2 versions of codemirror-element - one is for shadowdom and antoher one
is for shadydom.
