Martin Atkins d51921f085 core: Provider transformers don't use the set of all available providers
In earlier incarnations of these transformers we used the set of all
available providers for tasks such as generating implied provider
configuration nodes.

However, in modern Terraform we can extract all of the information we need
from the configuration itself, and so these transformers weren't actually
using this set of provider addresses.

These also ended up getting left behind as sets of string rather than sets
of addrs.Provider in our earlier refactoring work, which didn't really
matter because the result wasn't used anywhere anyway.

Rather than updating these to use addrs.Provider instead, I've just
removed the unused arguments entirely in the hope of making it easier to
see what inputs these transformers use to make their decisions.
