remove gate diffs and add memory report

[guipublic]

Description

Problem*

New project for memory report, to fork from noir-gates-diff, because the later can be used by noir developper (e.g noir lib creator) to track circuit size.

Summary*

Add the memory report, and remove the gate-diff actions from the forked repository
