Add capability to genereate the "zephyr-openamp-rsc-table" sample in yocto build.

This example demonstrates inter-processor communication based on a resource table,
with the objective of responding to the Linux kernel rpmsg sample.

This sample is compatible with the stm32mp157c_dk2 board.
The support of the board is also added in this series.
