This changes the fstab-generator to handle mounting of /usr/ a bit differently than before. Instead of immediately mounting the fs to /sysroot/usr/ we'll first mount it to /sysusr/usr/ and then add a separate bind mount that mounts it from /sysusr/usr/ to /sysroot/usr/. This way we can access /usr independently of the root fs, without for waiting to be mounted via the /sysusr/ hierarchy. This is useful for invoking systemd-repart while a root fs doesn't exist yet and for creating it, with partition data read from the /usr/ hierarchy. This introduces a new generic target initrd-usr-fs.target that may be used to generically order services against /sysusr/ to become available.
