Implement <selectedoption> for StylableSelect

This patch adds support for the <selectedoption> element to <select>.
The <selectedoption> element replaces its innerHTML with the ancestor
<select>'s selected <option>s innerHTML whenever the selected <option>
changes.

This patch implements it using a SynchronousMutationObserver with an
IsDescendantOf check, which might be slow. I added some comments in the
header with ideas of how to improve the performance.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
