cmd/coordinator: add a JSON mode to the /builders handler

And add a test that indirectly verifies that the BuildConfig and
HostConfig are JSON serializable. They weren't due to an exported func.

But that exported func shouldn't be exported, so unexport it and move
more policy into dashboard/builders.go. (There's been a number of
recent cleanup CLs to move all policy into dashboard/builders.go
instead of sprinkled all over the coordinator)

A future CL will use this JSON in gomote create.

Updates golang/go#30929
