Add procedural cosmetic operators remove() and upward()
***

New procedural cosmetic operator: `:remove()`

Related issue:
- https://github.com/gorhill/uBlock/issues/2252

The purpose is to outright remove elements from the
DOM tree. Since `:remove()` is an "action" operator,
it must only be used as a trailing operator (just
like the `:style()` operator).

AdGuard's cosmetic filter syntax `{ remove: true; }`
will be converted to uBO's `:remove()` operator
internally.

***

New procedural cosmetic operator: `:upward(...)`

The purpose is to lookup an ancestor element.

When used with an integer argument, it is synonym of
`:nth-ancestor()`, which will be deprecated and which
will no longer be supported once no longer used in
mainstream filter lists.

Filter lists maintainers must only use `:upward(int)`
instead of `:nth-ancestor(int)` once the new operator
become available in all stable releases of uBO.

`:upward()` can also accept a CSS selector as argument,
in which case the nearest ancestor which matches the
CSS selector will be selected.

Fix internal cosmetic filter being reported in the logger
Regression from:
- 62387fb87a

Repro steps were:
- Open the logger
- Navigate to `https://news.ycombinator.com/`
- Select an element using the element picker
- Click "Preview"

An attribute selector used internally by uBO to
hide targeted nodes was being reported in the
logger.

Add ability to report exception cosmetic filters in the logger
Related issue:
- https://github.com/gorhill/uBlock/issues/127

Additionally, the extended exception filters in the
logger will be rendered with a line-through to more
easily distinguish them from non-exception ones.

Also, opportunistically converted revisited code to
ES6 syntax.
