ASoC: Intel: avs: Declare path and its components

Declare representatives for all crucial elements which stream on ADSP
side is made of. That covers pipelines and modules subject which are
presented by struct avs_path_pipeline and avs_path_module respectively.
While struct avs_path_binding and struct avs_path do not represent any
object on firmware side directly, they are needed to help track the
interconnections and membership of every pipeline and module created.
