macOS: Add support for automatic updates using Sparkle.

Add support for automatic updates using the Sparkle framework. Add
FindSparkle.cmake and associated CMake plumbing. Add a public key and
other info to Info.plist.in. Add ui/macosx/sparkle_bridge.{h,m}, which
wraps the Sparkle API. Make code that's specific to WinSparkle
Windows-only.

Add Sparkle installation steps to the macos-setup scripts. Sparkle
prints a warning if your bundle is unsigned (which is the case during
development) so disable installing it by default.

Updating here takes a long time. We might be able to fix that by
shipping our DSYMs separately.
