Leander Kohler b3f79e3a2f arch: smbios: add tests for table serialization ...

Add unit tests that walk the SMBIOS binary layout in guest memory and
verify structure ordering, string-set encoding, and error paths.

Tests added:
  - smbios_chassis_empty_string_set_has_double_null: verify that
    a chassis with no strings emits the double-NUL terminator required
    by SMBIOS DSP0134 §6.1.3.
  - smbios_chassis_oem_strings_layout: verify the full chain
    (BIOS → System → Chassis → OEM → End) when a chassis asset tag and
    OEM strings are configured.
  - smbios_strings_terminators_default: verify the default table chain
    (BIOS → System → End) and check that string indices and string-set
    contents match for both structures.
  - smbios_strings_too_many: exercise alloc_index up to the u8 limit
    (255 strings) and verify the 256th is rejected.
  - smbios_uuid_invalid_rejected: ensure a malformed UUID string is
    rejected with Error::ParseUuid.
  - smbios_uuid_written_le: ensure the UUID is stored in little-endian
    byte order as required by SMBIOS Spec 7.2.1.
  - smbios_write_fails_with_too_small_memory: verify that setup_smbios
    fails with Error::WriteData when guest memory is too small to hold
    anything beyond the entry point.

All tests also succeed when run with miri:
  cargo +nightly miri test -p arch smbios
