Implement the font-optical-sizing property

Implement the CSS fonts property font-optical-sizing [1]. Typographic
optical sizing means that a font has slight variations in glyph contrast
to better optimize for legibility at different font sizes: The glyph
shapes vary between for example a headline font size and a body text
font size. The CSS font-optical-sizing property with its default value
of auto exists to automatically apply the current font size value to a
variable font's 'opsz' axis. This means, if a variable font supports the
'opsz' axis and optical sizing, the right value is automatically applied
without the need for an explicit font-variation-settings styling.

Intend to implement and ship:
