Pierrick Bouvier 9e65902904 include/semihosting/common-semi: extract common_semi API
We transform target/{arm,riscv}/common-semi-target.h headers to proper
compilation units, and use them in arm-compat-semi.c.

This way, we can include only the declaration header (which is target
agnostic), and selectively link the appropriate implementation based on
current target.
