meta-gbmc-staging: gbmc-sysinit: Refactor for multi-platform support

This commit refactors the gbmc-sysinit recipe to support multiple
platforms (server2 and server3) from a common code base.

- A new `gbmc-sysinit.inc` file has been created to hold common
  variables and tasks shared between the different platform recipes.

- The original `gbmc-sysinit.bb` has been renamed to
  `gbmc-sysinit_server2.bb` and updated to `require` the new `.inc`
  file. Its associated source files have been moved to a `server2/`
  subdirectory.

- A new `gbmc-sysinit_server3.bb` recipe has been added to support the
  server3 platform. This recipe also uses the common `.inc` file and
  adds its own set of systemd services and helper scripts, which are
  located in a new `server3/` subdirectory.

- The `transfer_bios_image_to_dram` function in the server3 helper
  script is intentionally left as a stub, as it is designed to be
  overridden by a machine-specific layer.

Tested: build and run on a Server3.0 machine and everything works as
expected.
