Have Directive::Log output format match println eval in acir gen

[vezenovm]

Description

There were some changes to the print formatting when making this println statements PR on Noir: noir-lang/noir#630.

Aim

There are some Logs that require witness information that can only be fetched during solving of the witness. The directive had to be made before making changes to Noir so that Noir could access Directive::Log during acir gen. During PR review of noir-lang/noir#630 some of the print formatting changed. We should bring Directive::Log up to speed.

Expected behavior

That hex output for printing during acir gen and when we solve the witness should match.

Bug

The output during witness solving is outdated.

To reproduce

If you try and log values that requires solving the witness you will see the difference.
