efi: Add ESRT to the EFI system table
The ESRT is initialised during efi_init_objlist after
efi_initialize_system_table().
The ESRT is recreated from scratch at the following events:
- successful UpdateCapsule;
- FMP instance install.
The code ensures that every ESRT entry has a unique fw_class value.
Limitations:
- The ESRT is not updated if an FMP instance is uninstalled;
- the fields image_type and flags are in the current implementation left
undefined. Setting these values will require a per-platform function
that returns the image_type/flags as a function of the image fw_class.
