Add a full-stack mint and burn test for Bitcoin and Monero

Fixes where ram_scanned is updated in processor. The prior version, while safe,
would redo massive amounts of work during periods of inactivity. It also hit an
undocumented invariant where get_eventuality_completions assumes new blocks,
yet redone work wouldn't have new blocks.

Modifies Monero's generate_blocks to return the hashes of the generated blocks.
