And remove some of the ::placeholder and ::cue hacks where we need to use
!important to make the property not apply for content but apply on UA sheets.
The comment about the white-space property was wrong, we don't enforce it with
!important in the UA stylesheets for <input> (we do for <textarea> though), so
I've kept the flag since it really applies.

Now if you add a new inherited, pref-controlled property, you must
declare whether it can have an effect on scrollbar styles. If no,
then the property will be skipped in the assertions that check
whether our cached styles are equal to those we would compute.

According to this resolved spec issue:
https://github.com/w3c/csswg-drafts/issues/2140,
we retire the 3-valued <position> on
1. `object-position`
2. `perspective-origin`,
3. `mask-position`
4. `circle()` and `ellipse()`
, but still keep the support for `background-position`.
Besides, I simply run this python script to generate the .ini file:
```
s = sys.argv[1] + ".ini"
with open(s, "w") as f:
f.write('[{}]\n'.format(sys.argv[1]))
f.write(' expected: FAIL\n')
f.write(' bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1559276\n')
```

Media controls
<strike>This is still highly WIP. It depends on #22743 and so it is based on top of it.
The basic controls functionality is there, but the layout is highly broken. There is a hack to at least make the controls render on top of the video, but it is not correctly positioned. The controls' div container ends up as sibbling of the media element in the flow tree while IIUC it should end up as a child.</strike>
- [X] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [X] These changes fix#22721 and fix#22720
There is at least an extra dependency to improve the functionality and visual aspect: #22728.
