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

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
heap 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.
