This commit implements the (mostly?) Linux compatible efidp_format_device_path and efidp_parse_device_path APIs. These are the only APIs exposed through this library. However, they are built on code from Tianocore's EDK2 MdePkg. They are brought in as new files here for reasons described in FreeBSD-update. Symbol versioning will be introduced to control what's exported from the EDK2 code. Some structural changes may be necessary when we move to sharing with sys/boot/efi. Sponsored by: Netflix
