LibWeb: Fire keypress event for Enter, Shift+Enter, and Ctrl+Enter keys

For web compat and interop with other engines, this change makes us fire
“keypress” events for the Enter key and for the combination of the Enter
key with the Shift or Ctrl keys — despite the fact the UI Events spec
states at https://w3c.github.io/uievents/#event-type-keypress it must be
fired “if and only if that key normally produces a character value”.

See https://github.com/w3c/uievents/issues/183#issuecomment-448091687
and https://github.com/w3c/uievents/issues/266#issuecomment-1887917756.
