ipc4: add ipc4 message support

There are two types of ipc4 message: global message and module message.
Ipc message is first decoded in handler.c and processed with the help
of helper.c to deal with pipeline message and module message.
Pipeline and Module messages are converted to sof pipeline and
component message.

Ipc4 pipeline message <------> ipc3 pipeline message
RUNNING       <------->   TRIGGER START
INIT + PAUSED <------->   PIPELINE COMPLETE
PAUSED        <------->   TRIGER_PAUSE
RESET         <------->   TRIGER_STOP + RESET
EOS           <------->   TRIGER_RELEASE

Ipc4 Module message <------> ipc3 module message
init module             <------->   create component
bind modules            <------->   connect components
module set_large_config <------->   component cmd
delete module           <------->   free component

There is no buffer module in ipc4 design and FW manages buffer for each
module while buffer component is defined by topology and create by ipc
message for ipc3 design. For ipc4 path, FW will create buffer when two
modules are bound since the buffer format can be gathered from source
& sink modules and the buffer can be connected to both modules.

Currently only part of ipc4 messages are processed and others will be done
in future.
