Move ColorProviderKey into its own header and make aliases

There are too many callers to migrate all at once, creating alises
in ColorProviderManager to facilitate the migration.

Many includes of color_provider_manager.h just need one of the types and
not the manager itself. Separate the Key types and declaration into its
own compilation units.

This allows targets to set ColorProviderKey values without depending
on the entirety of ui/color.
