Accessibility: Improve the color picker UI accessibility, interaction, and generated markup.
- Refactors the UI controls around the Iris color picker to output valid and semantic markup - Simplifies the way elements visibility gets toggled - Properly associates the visually hidden label with the color input field - Makes the toggle button a real button - Adds `aria-expanded` to the toggle button - Keeps focus on the toggle button instead of moving it to the color input field - Adds `aria-label` attributes to give better context to some controls - Removes a redundant title attribute - Keeps the toggle button text to "Select Color" instead of changing it to "Current Color" when a color is selected - Slightly improves the responsive view - CSS clean-up Fixes #39662. git-svn-id: https://develop.svn.wordpress.org/trunk@41329 602fd350-edb4-49c9-b593-d223f7449a82
