semihosting: reorganize semihosting commands 

the same semihosting handlers chain is declared twice:
 1. in src/target/armv4_5.c
 2. in src/target/riscv/riscv.c

to make it simpler we moved the declaration into
'src/target/semihosting_common.c' under semihosting_common_handlers[].
then we used this into both of armv4_5.c and riscv.c
