Increase the size of the style sharing cache to 31.
Still a lot of guesswork here, but this does seem to get us better sharing. See
https://bugzilla.mozilla.org/show_bug.cgi?id=1369621 for some data.

stylo: Bug 1335998 - Handle interpolation and accumulation of mismatched transform lists
These are the interdependent patches of Bug 1335998. We want to do interpolation and accumulation for mismatched transform lists, so introduce ComputedOperation::InterpolateMatrix and ComputedOperation::Accumulation. Both arms store the from_list and to_list, and resolve them until we have the layout information. For the Servo part, we haven't implemented how to read the transform lists in layout/fragment.rs, but I think it would be easy. (related issue #13267)

We convert ComputedOperation::{Accumulate, Interpolate}Matrix into gecko type
not on the main thread, so we cannot use nsCSSValueList_heap (which is not
thread safe so we cannot create it and destroy it on different threads).
Therefore, we use nsCSSValueSharedList to represent the cloned
from_list/to_list. In this patch, we also implement the reversing way,
i.e. Convert eCSSKeyword_{accumulate, interpolate}matrix into
{Accumulate, Interpolate}Matrix.
If we set the composite operation to accumulate, we may need to accumulate two
mismatched transform lists, and then to interpolate them. In order to
accumulate two mismatched transform lists, we also need the reference
box information, so use the same idea as that for interpolation. i.e.
use AccmulateMatrix to store it temporarily, and convert it into matrix
later.
We use this arm to store the interpolated result of two mismatched
transform lists, and we resolve it until we know the reference box size
(on Gecko side). The conversion from ComputedOperation::InterpolateMatrix
to eCSSKeyword_interpolatematrix will be implemented later in this patch series.
Stop parsing @supports rules before Delimiter::Bang
Fixes#15482
Shorthand parsing uses `parse_entirely`, so we have to ask it to stop before the `!important`.
An alternate fix is to not use `parse_entirely` there and ensuring that all callers of `PropertyDeclaration::parse_into()` check that the input is exhausted. Two of the three callers do that anyway because they check for `!important`.
We also weren't checking for the end of the parser for `CSS.supports()`.

Parent mismatch should not clear style sharing cache.
We can have cousins in the cache whose parent doesn't match ours, and other
cousins whose parent does. When we encounter one of the former, that's not a
reason to stop lookin for the latter.

Bump euclid to 0.13 and heapsize to 0.4
This is necessary for the serde 1.0 update.
