Massive refactor to accommodate RISC-V targets

- Refactored entire codebase (excluding the Insight component) to accommodate multiple target architectures (no longer specific to AVR)
- Deleted 'generate SVD' GDB monitor command - I will eventually move this functionality to the Bloom website
- Added unit size property to address spaces
- Many other changes which I couldn't be bothered to describe here
