More grid serialization and parsing fixes
These are the bugs I discovered while I was re-enabling the disabled grid mochitests. Now all grid mochitests are passing! Additionally I converted `Vec<CustomIdent>`'s into `Box<[CustomIdent]>`. We are storing so many line names in vectors. These should help a bit.

While decomposing a 3D matrix, we should normalize the 2nd row right after the
Y scale computation. However, we accidentally use the length of the 1st row to
do the normalization. This causes the wrong Scale3D function while decomposing,
and then leads to the wrong decomposed 3D matrix.
Here, we correct it by using the right value (the length of the 2nd row).

We have checks for these in the shorthand parsing side actually.
But if we need to serialize a group of longhand sub-properties for the shorthand,
we should be able to fail for invalid grammar gracefully. This patch adds these checks.
Store COW strings in CSS parser errors when possible.
This should be a straightforward performance improvement in pages with lots of CSS property values that the parser does not understand.

Replace all uses of the style::stylearc alias with servo_arc.
The `stylearc` alias is left there temporarilly and will be removed completely in a later commit/PR where also `components/style/gecko/generated/structs_{debug|release}.rs` are re-generated (they still use the old alias).

This causes a warning it today’s Nightly:
https://github.com/rust-lang/rust/issues/42868
… which makes the build fail because we use `#![deny(warnings)]`.
This warning is planned to become a hard error in a future Rust version.
