core: lib: scmi-server: Build a SCMI server from SCP-firmware

Adds build of an SCMI server library using SCP-firmware source tree
upon boolean configuration switch CFG_SCMI_SCPFW. Platform must set
the SCP firmware target product with CFG_SCMI_SCPFW_PRODUCT and the
root path of the SCP-firmware source tree with CFG_SCP_FIRMWARE.

CFG_SCMI_SCPFW and CFG_SCMI_MSG_DRIVERS are exclusives alternate
implementations of SCMI services. The former implements almost all
the SCMI specification while the later implements only basic SCMI
services.

SCP-firmware is configured with CMake as an external project to
generate the embedded module resource source and header files to
be built with SCP-firmware.

This commit integrates the 2 SCP-firmware products designed for OP-TEE
in SCP-firmware source tree. Product optee-fvp targets platform vexpress
flavors FVP and Qemus. Product optee-stm32mp1 targets platform stm32mp1.
