Select the unified RISC-V architecture implementation. BSPs that do
not select this option continue to use the legacy implementation while
the architecture migration is in progress.

Keep the saved exception frame on the interrupted thread stack, then
run C-level trap and interrupt handlers on a per-CPU interrupt stack.
This is recommended for MCU ports.
