dragonboards: Move firmware files to external vendor overlay package

Moving all the vendor binaries (including bootloader, qdl
and firmware binaries) to an external vendor.tgz package
to be downloaded from:
  https://releases.linaro.org/android/aosp-linaro-vendor-package/extract-linaro_devices-20220106.tgz

BUILD_BROKEN_ELF_PREBUILT_PRODUCT_COPY_FILES build flag is
used to copy a few vendor firmware files to ramdisk or
vendor_ramdisk to work-around the dependency of their
drivers on FW_LOADER_USER_HELPER_FALLBACK kernel config.
And for that we needed to bump up the boot and vendor_boot
partition sizes as well.

Also folded John's installer script changes into this patch.
