Upstream Corretto for easier maintenance

[WardsParadox]

This creates an upstream primary recipe set that others can base overrides off instead of creating whole new recipes when versions come out. This (combined with notifying other repos) should help reduce all the corretto recipes around.

This also supports the different architectures available to corretto downloads, and makes that work with Munki (should be validated by someone who uses it)

Likely going to move these to a different location. Disregard
