audio: component: move mod_alloc_ctx definition to new sof/ctx_alloc.h

mod_alloc_ctx is needed by many components and also soon by audio
components, so defining it in component.h will create circular
dependencies. To clean this up, move definition of struct mod_alloc_ctx
into the recently added ctx_alloc.h header.
