To support pipelines connection between cores, ipc4_create_buffer()
must be able to create buffer shared between source and sink
components created on different cores. ipc4_create_buffer() requires
source component obs size. When both source and sink components
created on same core, ipc4_create_buffer() is executed on that core,
otherwise it is executed of core 0 (IPC processing core). So for the
case when source and sink components are created on different cores
comp_get_attribute_remote() is used to receive source obs size.

bind/unbind handler must be called from core on which component was
created.
When both source and sink components are created on same core,
bind/unbind IPC is processed on that core. However, when connected
source and sink are on different cores, IPC is processed on core 0.
Hence comp_bind_remote() and comp_unbide_remote() is added to call
bind/unbide from proper core.

Add Asynchronous Messaging Service. This can be used to communicate between
modules.
Asynchronous Messages are one-way messages from one producer to one or
multiple registered consumers. Messages between modules on different
cores are sent through IDC. All inter-core communication must be proxied
by the main core.

The purpose of this commit is to separate the XTOS-specifc
code from the Zephyr-specifc code found in sof/drivers/idc.h.
