ASoC: SOF: ipc4-topology: Add payload to pipeline create messages

Browse source

Start adding payloads to pipeline create messages. The payload
contains information for payload specific memory configuration.

All non DP module instances within the same pipeline share the same
memory attributes and access the same resources. The new logic sums
interim, lifetime, and shared heap memory requirements together and
picks the highest stack requirement of all module instances belonging
to a pipeline. These pipeline specific attributes are sent as struct
sof_ipc4_glb_pipe_payload payload in pipeline's create message.

The idea is to pass common memory configuration for all the Low
Latency modules in the pipeline in pipeline create message payload.

The Data Processing module instances will still have an individual
memory configuration in struct sof_ipc4_mod_init_ext_dp_memory_data
payloads as before. In their payload everything is as it was before,
all attributes are copied directly from their topology attributes.
