initramfs cpio tools had been subject of several recent discussions on
linux-kbuild.  Let's get two minor steps forward by enabling a
top-level target for building gen_init_cpio w/o the need of a valid
kbuild configuration [1] and move the tools for generating the builtin
initramfs from usr/ to scripts/ [2].

Changes in v2:
  * Build gen_init_cpio only if CONFIG_BLK_DEV_INITRD (Thomas)
  * Keep underscore top-level target name (scripts_gen_init_cpio)
    (Thomas)
  * Link to v1: https://patch.msgid.link/20260309-move-gen_init_cpio-to-scripts-v1-0-0c5059b1ec5b@kernel.org
