Change Plugin{} element API to use enums for features

Notably, this change also sets up Map{} elements to delay probing their
set plugin until the plugin is complete, so that requiredFeatures
can function correctly without support for changing plugins
dynamically.

Please note: the necessary docs for these new methods and updates
to the already extant docs related to this will be in a separate
commit.
