[css-fonts] CSSFontFaceDescriptors is missing descriptor attributes

[cdoublev]

CSSFontFaceDescriptors seems to be missing font-weight (not fontWeight) and font-stretch/fontStretch (legacy).

CSS Fonts 5 may also missing a partial interface definition with font-size/fontSize, size-adjust/sizeAdjust, and *-override/*Override.

A simpler alternative is proposed in #10105.

Agreed, the missing font-weight looks like a simple error and the legacy values are an over-eager rename rather than a deprecation, which was the csswg resolution.

I don't follow about the "simpler alternative".

CSSFontFaceDescriptors attributes would be defined generically, like CSSStyleProperties attributes.

For each CSS descriptor descriptor that is a supported CSS descriptor accepted in @font-face, the following partial interface applies where _camel_cased_attribute is obtained by running the CSS property to IDL attribute algorithm for descriptor.

partial interface CSSFontFaceDescriptors {
  attribute [LegacyNullToEmptyString] CSSOMString _camel_cased_attribute;
};

And similarly for dashed attributes.
