9a31c3d56b LibWeb/CSS: Introduce CSSNumericValue and CSSUnitValue type stubs
CSS-Typed-OM has the following hierarchy:

CSSStyleValue
- CSSNumericValue
  - CSSUnitValue
  - CSSMathValue
    - ...various math functions...

Somewhat unintuitively, numbers are also stored using CSSUnitValue with
`unit = "number"`.

There are no distinct classes for LengthStyleValue, etc in the spec, but
they're convenient for us, so they are implemented as subclasses of
CSSUnitValue, at least for now.

1160d8186b LibWeb: Implement IntegerStyleValue, for holding <integer>
Having one StyleValue for `<number>` and `<integer>` is making user code
more complicated than it needs to be. We know based on the property
being parsed, whether it wants a `<number>` or an `<integer>`, so we
can use separate StyleValue types for these.
