Reland "[remoting host] Implement RemoteWebAuthnExtensionNotifier"

This is a reland of commit 8fecb333d0e2fac06e64922a73eafff7b28d41b6

Fixed broken unit tests that call CreateUniqueTempDir() inside
DCHECK(), which gets stripped off in non-debug builds, by simply
replacing DCHECK()s with EXPECT_TRUE()s.

Original change's description:
> [remoting host] Implement RemoteWebAuthnExtensionNotifier
>
> This CL provides implementation for the RemoteWebAuthnExtensionNotifier
> class, which is based on the webAuthenticationProxy
> onRemoteSessionStateChange API introduced in crrev.com/c/3514116. The
> gist is that Chrome will watch for changes of some files in a specific
> directory, and whenever these files are changed, the
> onRemoteSessionStateChange event will be triggered on the Chrome
> extension.

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.
