Subject: Issue #24585: Enables build-to-build upgrades that preserve settings.
 Rather than using Burn "Persisted" variables we now add registry keys for
 each added feature. These can be detected by the installer regardless of
 which version installed them, and we use this for Modify and Upgrade. In
 particular, Upgrades can't access the Persisted variables, but can find
 well-known registry keys. There are also some changes to the bootstrap app to
 properly handle upgrades. Finally, a few minor improvements to the Windows
 build to keep things tidier.
