Remove unimplemented -webkit-appearance keywords

This CL removes the following keywords:
* button-bevel
* caret
* listitem
* media-controls-background
* media-controls-fullscreen-background
* media-current-time-display
* media-enter-fullscreen-button
* media-exit-fullscreen-button
* media-mute-button
* media-overlay-play-button
* media-play-button
* media-time-remaining-display
* media-toggle-closed-captions-button
* media-volume-slider-container
* menulist-textfield
* menulist-text
* progress-bar-value

They have been deprecated since M74.

New FAIL lines in appearance-cssom-001-expected.txt are expected.
We'll update the css-ui specification and tests after the removal.
