ui/base: move clipboard to own folder.

ClipboardOzone needs to depend on ui/ozone in order to call
OzonePlatform::GetPlatformClipboard, but as long as all the base::clipboard
classes are part of ui/base source set, and ui/ozone depends on
ui/base, it's impossible to depend on ui/ozone. And that
creates a circular dependency.

Thus, factor out clipboard source files and make appropriate source sets,
which will be used by clients on their needs instead of depending on
everything.
