roachtest: exercise drop of 2tb table

[tbg]

This roachtest replicates the scenario described in #24029 and serves
as the basis for experimentation.

It currently fails:

I could use a bit more commentary in this test. It took me a few reads to understand that the store dumps are large, while the import into tinybank is small.

Do you plan to merge this? Perhaps mark it as skipped.

TFTR! I'll merge this (and I'll leave it unskipped for a few days, just to see that it reliably fails and that I didn't introduce a bug in the home stretch).
