Bug: Support line wrapping

[bradymadden97]

Currently we assume lines do not wrap. If an editor wraps has a fixed width and causes lines to wrap (ex. EditorView.lineWrapping) it will throw off a number of assumptions we make

• We don't render the wrapped text/blocks on a new line
• We calculate the viewport overlay incorrectly
• We scroll incorrectly

Will likely require using the character width & the scrollDOM width
