cpukit: RISC-V - make riscv32 code work for riscv64 - v2
- Use #ifdefs for 32/64 bit code
- Use unsigned long which is 32-bit on riscv32 and 64-bit on riscv64 (register size)
- Move the code to a new shared riscv folder to be shared between riscv32 and riscv64
- Rename RTEMS_CPU extracted from command line to shared riscv target s/riscv*/riscv
Update #3109
