Subject: [PATCH] Recognize 'optimizespeed' and 'optimizequality' for
 'image-rendering'

In css_properties.json5 we list these keywords but we didn't recognize
them when parsing. Synchronize the two lists.

CSS Images L3 says the following about these two values:

  "This property previously accepted the values optimizeSpeed and
   optimizeQuality. These are now deprecated; a user agent must accept
   them as valid values but must treat them as having the same behavior
   as pixelated and auto respectively, and authors must not use them."
