dev-manual, ref-manual: Systemd-boot: Update documents for new EFI bootloader

Fixes [YOCTO #9707]

* Replaced gummiboot with systemd-boot in the dev-manual
* Replaced the gummiboot class with a new systemd-boot class
* Replaced the appropriate gummiboot variables in the glossary
  with new variables SYSTEMD_BOOT_CFG, SYSTEMD_BOOT_ENTRIES,
  and SYSTEMD_BOOT_TIMEOUT.
