rump_cgd

[Steven Harp]

Is rump_cgd (block encrypted devices introduced ~14.05) still
supported/operational in Genode 18.x?  Issue #2224 mentions
"not converted" in transition to new base API [1], and #2778 seems
to have removed the 'tool/rump' script (which was handy to
prepare encrypted volumes) [2].
