Add support for some missing properties and values

[hacknug]

This PR adds support for multiple valid CSS properties and values like clip-path, font-feature-settings, and text-overflow. It also fixes some already supported properties that weren't matching correctly like object-fit and object-position. See commits for full reference.

Let me know if you'd like me to make any changes or add something to this.

I was taking another look at this since I needed to add more property names and values to the list and thought that maybe it'd be better to use language-css's regex for this things? They have a list with way more properties than this package does and adding them one by one would be very tedious.
