Peter Ujfalusi 3bc70b6251 sof-ctl: Add initial support for handling blobs for IPC4 
For IPC4 we are re-using the sof_abi_hdr to encapsulate the blob from/to
user space with minor deviation from IPC3:
- ABI magic is different
- the type is used as param_id in IPC4 (it carries the same functionality)

The IPC type can be specified with -i and defaults to 3 (IPC3).

-p is added as a new option for param_id, but -t and -p will do the same
thing.

After reading a blob, print a message for unexpected ABI magic number, but
do not block the execution.

To generate a header for 100 bytes payload:

For IPC3:
sof-ctl -g 100 -t 2
sof-ctl -i 3 -g 100 -t 2

For IPC4:
sof-ctl -i 4 -g 100 -p 2

How to use sof-ctl tool
=========================

This tool helps to access the ext bytes or tlv bytes control of SOF
components (like equalizer eq_iir and eq_fir). Please find the documentation
in https://thesofproject.github.io/latest/getting_started/index.html for
more information.
