SWD Debug support in VexRiscv

Functional SWD debugging support for VexRiscv/VexiiRiscv

The VexRiscv-Debug project aims to extend the popular open-source VexRiscv RISC-V soft CPU core with functional debugging support enabling essential development and bring-up capabilities for developers building debuggable RISC-V SoCs on custom ASIC or FPGA platforms. This includes making Vexriscv fully Riscv Debug specification compliant and additionally adding support for Serial Wire Debug (SWD), which is a widely used industry specification set forth by ARM.
