part_efi: move uuid<->string conversion functions into lib/uuid.c

This commit introduces cleanup for uuid library.
Changes:
- move uuid<->string conversion functions into lib/uuid.c so they can be
  used by code outside part_efi.c.
- rename uuid_string() to uuid_bin_to_str() for consistency with existing
  uuid_str_to_bin()
- add an error return code to uuid_str_to_bin()
- update existing code to the new library functions.
