WebUI: Fix memory leak

See #22734, there is a memory leak in the MooTools .destroy(), this replaces all uses of that with the browser native .remove().

This also overrides the MooTools Document.id function, which is used by $(id). The original function always allocates an ID to elements it selects, the override doesn't, and is also a little more efficient.

Closes #22734.
PR  #22754.
