LibWeb: Fire input events in .execCommand()

Browse source 
We do not fire `beforeinput` events since other browsers do not seem to
do so either.

The spec asks us to check whether a command's action modified the DOM
tree. This means adding or removing nodes and attributes, or changing
character data anywhere in the tree. We have
`Document::dom_tree_version()` for node updates, but for character data
a new version number is introduced that allows us to easily keep track
of any text changes in the entire tree.
