Reland "[CT] Hashdance: Pick SCT and plumb its leaf hash"

This is a reland of 837d8719146ed8579c08857fc6c014b12645355a

Fell for the classic chromium blunder of putting code that always needs
to run inside a DCHECK.

Original change's description:
> [CT] Hashdance: Pick SCT and plumb its leaf hash
>
> If SCT reporting is in hashdance mode, have SCTAuditingHandler pick a
> single SCT and calculate its leaf hash before plumbing the SCT report
> down to the SCTAuditingReporter. The leaf hash is then stored with
> SCTAuditingReporter and serialized / deserialized accordingly.
>
> To avoid having SCTAuditingCache know about the SCT auditing mode, the
> dependency between SCTAuditingCache and SCTAuditingHandler is inverted
> (reillyg@ suggested this change in an earlier CL as well). Most of the
> changed LOCs in this CL are therefore related to moving the relevant
> tests.
