Add AMD firmware parser

Based on the open source AMDFWTOOL available here:
https://github.com/coreboot/coreboot/tree/main/util/amdfwtool

TODO:
- Merge duplicated regions
  There can be multiple L2 directory tables, for A/B recovery or
  to support different SoC SKUs. They point to the same regions,
  causing the same area to be shown multiple times in the parsed
  image.
- Better quirks support
  PSP hardcodes certain sizes and address types for some files.
  The parser might thus fail, even though it works on real hardware.
