Since all SCMI transports have been made standalone drivers, remove all the
core SCMI stack legacy support that was needed to run transports as built
into the stack.

Extend the core SCMI stack with structures and methods to allow for
transports to be split out as standalone drivers, while still supporting
old style transports, defined as built into the SCMI core stack.
No functional change.

Introduce a pair of structures initialized to contain all the existing
packet handling helpers, both for transports based on shared memory
and messages.
No functional change.

Add abstractions for future transports using message passing, such as
virtio. Derive the abstractions from the shared memory abstractions.
Abstract the transport SDU through the opaque struct scmi_msg_payld.
Also enable the transport to determine all other required information
about the transport SDU.
