Missing dynamic layout features

[JulianGCalderon]

Missing dynamic layout features

Solves #1834

Features

• dynamic memory units per step. This attributes used to be a fixed constant MEMORY_UNITS_PER_STEP. This PR changes this to use a CairoLayout attribute instead
• negative log diluted units per step. I added an attribute to DilutedPoolInstanceDef that indicates if log_units_per_step is negative or positive.
• low ratio builtins with ratio den. Builtins that can have a low ratio now use the LowRatio struct, which has a denominator and a numerator.
• dynamic cpu component step. Currently not used

Checklist

• Linked to Github Issue
• Unit tests added
• Integration tests added.
• This change requires new documentation.
  • Documentation has been added/updated.
  • CHANGELOG has been updated.

Nice one @JulianGCalderon !!!
Also, can you add a little documentation in the readme explaining how to use the dynamic layout
