The phrase "I am done" is a complete thought. It means you have finished an implied task or activity, and it's not important to clarify what that task was.
"I have done" means the same thing in British English. The task implied has usually already been referenced in conversation.
For example:
Jill: "Dear, the light over the stove won't work."
Jack: "Have you tried changing the light bulb?"
Jill: "Yes, I have done, and it still isn't working. Will you check the fuse box?"
