LibWeb: Make @counter-style tree-scoped
...
This was a pretty straightforward change of storing registered counter
styles on the relevant `StyleScope`s and resolving by following the
process to dereference a global tree-scoped name, the only things of
note are:
- We only define predefined counter styles (e.g. decimal) on the
document's scope (since otherwise overrides in outer scopes would
themselves be overriden).
- When registering counter styles we don't have the full list of
extendable styles so we defer fallback to "decimal" for undefined
styles until `CounterStyle::from_counter_style_definition`.

LibWeb: Cache hardcoded counter styles
...
This avoids a bunch of string validations reducing time spent in
`CounterStyle::disc()` from ~3% to ~0.01% when loading

LibWeb: Clamp CSS <integer> value to i32 at parse time
...
This matches the behavior of other browsers. Previously we implemented
this at used-value time for z-index specifically.

LibWeb: Make CounterStyle ref counted
...
Previously we just passed around a reference to the `CounterStyle`
stored on `Document::registered_counter_styles` but this won't be
possible for anonymous counter styles (i.e. those created by the
`<symbols()>` function)

LibWeb: Support Chinese counter styles
...
We implement the extended version of this algorithm but don't take full
advantage of it since we are limited to an i32 for our counter values.

LibWeb: Use i64 when generating initial counter representation
...
This means that we can correctly represent the absolute value of INT_MIN
(2147483648) rather than clamping it to an i32 (2147483647)
