gma: Rename Config_Type => Pipe_Config

This was long overdue. Originally, we only had one type of `confi-
guration` but those times are over. Thus, rename `Config_Type` to
`Pipe_Config` along with `Configs_Type` to `Pipe_Configs` and
`Config_Index` to `Pipe_Index` to give them more meaningful names.
