arch: support decouple signal related function from arch code

make the following arch can work when signal is disabled:
1. arch/arm
2. arm/arm64
3. arch/avr
4. arch/z80
5. arch/mips
6. arch/x86
7. arch/misoc
8. arch/tricore
9. arch/risc-v
10. arch/sim
11. arch/z16
12. arch/xtensa
13. arch/or1k
14. archrenesas
15. arch/sparc
