Allow devShell to be a package def or take args

Browse Source 
Previously, devShell was inconsistent when setting it to a function.
When setting directly, a function was assumed to be a package definition
and was used to set devShells.default directly. When auto-loading, a
function was assumed to take module args, and result in config (not a
derivation).

This now enables both behaviors in either case by detecting if a
function is a package definition or if it expects module args and
handling it accordingly.
