target/riscv: Regenerate debug_defines.{c,h} from current riscv-debug-spec

This pulls in some improvements from the riscv-debug-spec repo, and
cleans up the licensing (riscv-debug-spec changed the license to dual
CC-BY-4.0 and BSD-2-Clause specifically to make sure the generated
debug_defines files don't conflict with OpenOCD licensing)
