Fix RTL rendering of SELECT on macOS and input[type=color] on all platforms.
We had two issues.
* 'menulist' and 'menulist-button' appearances were not RTL-aware on macOS
They are used for <select> and <input type=color list>.
They were always rendered in LTR.
* Paddings of <input type=color list> were not RTL-aware on all platforms.
This CL fixes them.
