Correct bloom hash bitpacking documentation
The two 12 bit keys add to 24 bits, which leaves 8 bits free in each word. (And 8 * 3 = 24, to pack in the fourth hash.)

When stylo is not enabled in Gecko, the global state initialization
still creates the style thread pool, even when it's not going to be
used. This wastes address space and a little memory.

Fix several bugs related to scrolling
* scrollLeft/scrollTop returned values of parent or even document root
Only the scroll of the node itself is returned. Otherwise 0.0.
* Scrolling via script had set viewport.
This resulted in other nodes appearing scrolled.
Now scroll_offsets are updated with correct node id.
These bugs caused other odd behavior like both body and
document.documentElement being scrolled or the view for scrolled
elements jumping.
Also try scrolling this [example page](https://pyfisch.org/stuff/scrolltest.html) in servo with and without this change.

We already call Document::invalidate_style_sheets and set
the stylesheet member to a new Stylesheet. This matches the behavior of
Firefox, and means the new CSSStyleSheet you get from accessing .sheet
from JS will be correct instead of stale.
(::get_cssom_stylesheet already tries to use the new Stylesheet, but
MutNullableJS::or_init is called, so if we already created a
CSSStyleSheet we will continue to return that one).
Currently we check `if not (osmesa_path and glapi_path)` after using
`path.join`. It seems we actually want to check whether
`find_dep_path_newest` returns something, because if calls to that
function fail, we'll instead get an error from `path.join` about
`NoneType` not having attribute `endswith` (it expects a string), which
preempts this check.
`ElementStyles` holds an optional list of values for each eager pseudo-element.
However, the type was declared as a slice instead of a fixed size array, so an
extra 8 bytes were being allocated to hold the size, even though it never
changes.
Moving the constant size into the type reduces `ElementStyles` and `ElementData`
by 8 bytes.

Before this change, the `ComputedStyle` struct that is part of permanent style
data per element holds 2 `StrongRuleNode`s (unvisited and visited) and 2
`Arc<ComputedValues>` (unvisited and visited).
Both rule nodes and the visited values don't actually need to be here. This
patch moves these 3 to new temporary storage in `CascadeInputs` on
`CurrentElementInfo` during the match and cascade process. Rule nodes are
pushed down inside the `ComputedValues` for later access after the cascade.
(Visited values were already available there.)
The permanent style data per element now has just the `Arc<ComputedValues>` for
itself and eager pseudo-elements (plus the `RestyleHint`).

In the patch after this, the existing `ComputedStyle` type is renamed and
repurposed as temporary storage of inputs for the cascade. To make it a bit
easier to follow what code is new, this patch starts by copying `ComputedStyle`
to context.rs without changes.
