d0f80b40b2 LibWeb: Reimplement CalculatedStyleValue as a calculation node tree 
VALUES-4 defines the internal representation of `calc()` as a tree of
calculation nodes. ( https://www.w3.org/TR/css-values-4/#calc-internal )

VALUES-3 lacked any definition here, so we had our own ad-hoc
implementation based around the spec grammar. This commit replaces that
with CalculationNodes representing each possible node in the tree.

There are no intended functional changes, though we do now support
nested calc() which previously did not work. For example:
    `width: calc( 42 * calc(3 + 7) );`

I have added an example of this to our test page.

A couple of the layout tests that used `calc()` now return values that
are 0.5px different from before. There's no visual difference, so I
have updated the tests to use the new results.

1352f8820b LibWeb: Simplify CalculatedStyleValue types to match CSS-VALUES-4 :^) 
Level 4 drops the limitations of what types can be a denominator, which
means `<calc-number-sum>`, `<calc-number-product>` and
`<calc-number-value>` all go away.

This selects an element if it is either a built-in element, or an
upgraded custom element.

bed55ac669 LibWeb: Parse and plumb background-position-x/y 
This parses the new background-position-x/y longhands and properly
hooks up them up. This requires converting PositionStyleValue to
just contain two EdgeStyleValues so that it can be easily expanded
into the longhands.

d64ddeaec4 LibWeb: Move PositionValue into its own files 
It's in Position.{h,cpp} because it represents a <position> in CSS, even
though it's currently named PositionValue to avoid collisions.

bcebca62d3 LibWeb: Move CSS::EdgeRect into its own files 
Also remove the unused StyleValue::to_rect() because an EdgeRect is only
ever held by a RectStyleValue.

7a1a97f153 LibWeb: Remove CalculatedStyleValue from Angle 
...and replace it with AngleOrCalculated.

This has the nice bonus effect of actually handling `calc()` for angles
in a transform function. :^) (Previously we just would have asserted.)
