material-v0.3.9

IconButton shows its label as a tooltip. An icon-only button already used label as its accessible name, but sighted mouse users couldn't see it, so a generated toolbar of icons was guesswork. The label now also appears as a Material tooltip on hover and focus. The accessible name is unchanged, and screen readers still read the label once: the CDK adds no aria-describedby when the tooltip repeats the aria-label. The catalog's description of IconButton now mentions the tooltip.

Thanks to @vns-agm for this one (#4), the catalog's first outside contribution. A disabled IconButton doesn't show the tooltip yet. That is #5, open as a good first issue.
