arch: common: dedicated SEMIHOST symbol

Browse source 
Control the usage of semihosting with a dedicated symbol, instead of
implying semihosting from the usage of `SEMIHOST_CONSOLE`. This allows
semihosting to be used without the semihost console.

Enable this option to use semihosting for console.
Semihosting is a mechanism that enables code running on an ARM or
RISC-V target to communicate and use the Input/Output facilities
on a host computer that is running a debugger.
Additional information can be found in:
https://developer.arm.com/docs/dui0471/k/what-is-semihosting/what-is-semihosting
https://github.com/riscv/riscv-semihosting-spec/blob/main/riscv-semihosting-spec.adoc
This option is compatible with hardware and with QEMU, through the
(automatic) use of the -semihosting-config switch when invoking it.
See SEMIHOST for a more complete description of semihosting.
