ASoC: SOF: ipc4-loader: remove the CPC check warnings

Warnings related to missing data in firmware manifest have
proven to be too verbose. This relates to description of
DSP module cost expressed in cycles per chunk (CPC). If
a matching value is not found in the manifest, kernel will
pass a zero value and DSP firmware will use a conservative
value in its place.

Downgrade the warnings to dev_dbg().

ASoC: SOF: ipc4-loader/topology: Query the CPC value from manifest

The manifest's firmware module configuration section contains the measured
CPC values along with a matching IBS/OBS values.

The CPC can be looked up by looking for a matching IBS/OBS entry.
In case of multiple matches we will use the highest CPC value.

If there is no mod_cfg or no CPC value (all 0) or no match was found then
print warning message and use 0 as CPC value.

ASoC: SOF: ipc4: Convert the firmware handling (loader) to library convention

With IPC4 each DSP loadable binary is a library, which contains
ext_manifest section and loadable modules.
The basefw is no exception, it is always library 0 and it can contain
several modules, depending on the firmware build.

The current code assumes only one binary, which is the basefw and has no
concept of libraries.
This patch introduces the library+modules abstraction and represents the
basefw as library for the IPC4 loader codebase.
The basefw loading and handling is not changing, it is still done by the
generic code, but it's information is cloned under the library
representation.

The libraries are managed via XArray to offload the list and ID management.

ASoC: SOF: ipc4: Add support for mtrace log extraction

One of the debugging/logging features for an IPC4 based firmware is the use
of the debug window to deliver log messages to host via the shared SRAM.

The initial implementation of the mtrace supports only TGL/MTL style of
logging, but can be extended to support other types, like APL, SKL, CNL,
etc.

The window is split into 16 'slots' where the first slot contains the
descriptors for the remaining 15 slots.

Each DSP core logs to a separate slot and the slot allocation is not fixed,
we can not assume that the first slot is always used by core0 for example.

The firmware sends LOG_BUFFER_STATUS message when new log batch is
available from one of the cores (after it updated the write_ptr in the
given slot).
Host should update the read_ptr in the same slot when it has taken out log
data.

The patch also updates the sof_ipc4_fw_data struct with parameters needed
for the mtrace to be enabled and used safely.
