Support shadow-piercing combinator `>>>` in `trusted-click-element` 

Related issue:
https://github.com/uBlockOrigin/uBlock-issues/issues/2971

Example usage:

...##+js(trusted-trusted-click-element, #cmpwrapper >>> .cmpboxbtnyes)

The substring before ` >>> ` must select an element with a non-null
shadow root, in which case the substring after ` >>> ` will be used
to find the element in the targeted shadow root. ` >>> ` can be used
recursively when multiple shadow root must be pierced.
