extensions: `uefi-edk2-rk3588`: deploy edk2 (not u-boot) for rk3588 boards
- this extension is _100% optional_ and shouldn't adversely affect any builds if not enabled - requires `UEFI_EDK2_BOARD_ID` to be set in board file, so we know which UEFI/edk2 build to use - it finds the latest edk2 version from GitHub automatically (currently `v0.9.1`) - it downloads (and caches) the correct edk2 build image automatically - if forces certain aspects of the image: - must use GPT partitioning - must NOT use a separate /boot partition - it _disables_ the building and deploying of u-boot _completely_ (thus blobs etc are from edk2) - it creates a GPT `"uboot"` partition pointing to edk2's FIT, required by SPL - this extension: - automatically enables 'grub-with-dtb' - automatically enable 'initramfs-usb-gadget-ums', to compensate for lack of ums/rockusb since we dont have u-boot anymore
