There are a few canvas2d-related dependencies that haven't updated, but they
only use euclid internally so that's not blocking landing the rest of the
changes.
Given the size of this patch, I think it's useful to get this landed as-is.
This is the easy fix.
The hard fix (outlined in the comment) would be nice, but I don't think this bug
alone justifies it.

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')
```

And move the useful bits of it somewhere else (ServoStyleConstInlines.h for the
inline function definitions, and nsFrame.cpp for the static assertions).

We clamp earlier (parse time rather than computed value time), but that's the
only behavior change, which I think doesn't really matter.

This needs https://github.com/eqrion/cbindgen/pull/362, but I expect it to be
uncontroversial. I'll add a patch to this bug when it's merged to update it.
cbindgen historically didn't include these, but it turns out to be pretty useful
to generate constants for the style crate (since the binding crate is
`servo/ports/geckolib`).
An alternative is to get a completely different cbindgen-generated header for
these, but that seems a bit wasteful. This generates the constants with the
Style prefix (so we'll get `StyleMAX_GRID_LINE` for example), which is very
ugly. But we probably want to eventually stop using the Style prefix and use a
namespace instead, plus it's trivial to do `auto kMaxLine = StyleMAX_GRID_LINE`,
for example, so it's probably not a huge deal.
Another alternative would be to use associated consts, which _are_ generated by
cbindgen. Something like:
```
struct GridConstants([u8; 0]);
impl GridConstants {
const MAX_GRID_LINE: i32 = 10000;
}
```
Which would yield something like:
```
static const int32 StyleGridConstants_MAX_GRID_LINE = 10000;
```
I'm not sure if you find it preferrable, but I'm also happy to change it in a
follow-up to use this.
We need to fix a few manual C++ function signature definitions to match the C++
declaration.

Option<> is not FFI-safe, so if we want to use the same representation
everywhere we need to get rid of it. This also makes it take the same amount of
memory as the C++ representation, and it's not very complex, I'd think.

This doesn't change the way C++ code uses static prefs. But it does slightly
change how Rust code uses static prefs, specifically the name generated by
bindgen is slightly different.
The commit also improves some comments.
