Replace spsc_pbuf with pbuf implementation dedicated to
be used by IcMsg based backends.
The pbuf is written on top of simple read/write semantics
with minimal footprint and code complexity

Remove nocopy feature from icmsg_me backend.
The backend is not meant to be used to send big
data chunks thus no-copy feature is removed.
If one wants to use no-copy it is recommended
to use icmsg_me only for control messages while
allocator will shall be written seperately.

This patchset is doing three things:
1. It is fixing the bogus algorithm to find the optimal number of
descriptors for a given memory size.
2. It is changing values for VDEV_STATUS_SIZE and
IPC_SERVICE_STATIC_VRINGS_ALIGNMENT to better align to a usual cache
line size.
3. RX/TX VRINGs are now correctly aligned to MEM_ALIGNMENT (and cache
line alignment).

The multi-endpoint backend of the ipc_service subsystem contains two
roles with separated implementations: initiator and follower. There
was many code duplications for both roles. This patch introduces a new
IPC library: icmsg_me containing common code extracted from both roles
and encapsulating access to common data fields.

Separate ipc_service libraries Kconfig entries from ipc_service backend
entries. IPC_SERVICE_BACKEND_ICMSG_BOND_NOTIFY_REPEAT_TO_MS is renamed
to drop BACKEND part, because this entry applies to a library, not to
one backend. Icmsg related entries are grouped now in a menuconfig for
cleaner presentation in configuration editors.
