Expand font-weight and font-stretch to take any number
https://bugs.webkit.org/show_bug.cgi?id=168889

Reviewed by Simon Fraser.

Source/WebCore:

This patch expands parsing support for font-weight and font-stretch so that they can accept
numbers in addition to the keyword values they accepted previously. Eventually, these numbers
will be used as inputs to select variation fonts; however, in this patch, the values are just
parsed and held in our internal data model. This means that this patch doesn't actually change
the general behavior of WebKit; instead, it parses new values, outputs them (via
getComputedStyle() and similar functions), and provides them as input to our preexisting font
selection algorithm.

This patch doesn't actually modify anything algorithmically, and therefore, it doesn't include
any additional tests for the font selection algorithm. Instead, it tests the parsing of the
newly accepted values (both input and output).

Because our internal data model needs to hold numbers now, this patch also completely eliminates
the FontWidth, FontItalic, and FontTraitsMask enum values in favor of FontSelectionValues (which
can hold numbers instead of individual enum values). Therefore, every place which we were using
these enum values is migrated in this patch to using FontSelectionValues instead.
