Refactor smbios cmd print functions to match the content defined by the specification. 2. Add new print functions for Type 3, 4 and 7. 3. Remove the fallback string "Not specified" from smbios_get_string, as the spec requires a NULL output for those undefined strings. 4. Update the test_cmd_smbios_sandbox pytest expected result to align with the smbios library changes and add new pytest test_cmd_smbios_sysinfo_verbose to test the verbose smbios output.

It hardcodes values instead of exposing values from the device. It does not reserve the space to support dynamic length for contained object handles or elements and misses the handling of a few of fields. The refactoring of this patch includes: 1. Expose values from device via sysinfo interface. 2. Replace smbios_add_prop with smbios_add_prop_si to allow getting string values from sysinfo. 3. Add smbios_get_val_si to get values from sysinfo or device tree. 4. Use sysinfo_get_data to get data area. 5. Reserve the space of contained object handles and elements. 6.
