RISC-V: Add ptrace support for vectors
This patch add back the ptrace support with the following fix:
- Define NT_RISCV_CSR and re-number NT_RISCV_VECTOR to prevent
conflicting with gdb's NT_RISCV_CSR.
- Use struct __riscv_v_regset_state to handle ptrace requests
Since gdb does not directly include the note description header in
Linux and has already defined NT_RISCV_CSR as 0x900, we decide to
sync with gdb and renumber NT_RISCV_VECTOR to solve and prevent future
conflicts.
