Some "HTML editor commands" are stateful due to storing tag name to handle it
with specific command. However, we can make it stateless with retrieving
tag name from command name once per command only when it's necessary. The
runtime cost must be really cheap since we can map it with hash table.
This patch makes them stateless and singleton classes. So, we can save
footprint and allocation runtime cost with this change.

`nsIControllerCommandTable` isn't implemented with JS even in comm-central nor
BlueGriffon. Therefore, we can make it a builtinclass.
Additionally, it's inherited only by nsControllerCommandTable. So, all users
in C++ can treat the concrete class directly.

HTMLEditorController and HTMLEditorCommands is for execCommand, so we should
move from composer to libeditor since HTML editor code is in libeditor.
