Ramdisk: Enable detaching bootconfig from initrd

This is the reverse of appending bootconfigs to initrd.
initrd_bootconfig detach-bootconfig takes initrd_with_bootconfig as
input & outputs the containing ramdisk & bootconfigs.

This is required because our signing infrastructure requires changing
vbmeta related configs (when images are resigned using a different key).
This can be achieved by detaching the configs, modifying them &
re-attaching them.

Bug: 245277660
Test: Attach & then detach bootconfigs to initrd & the diff the
artifacts.
