Add allow_missing_builtins flag

[fmoletta]

This new flag will skip the check that all builtins used by the program need to be present in the selected layout if enabled. It will also be enabled by default when running in proof_mode.
This flag has been added to : CLI, CairoRunConfig, CairoRunner::initialize & CairoRunner::initialize_builtins
Documentation has been added/updated
Other changes: Removed outdated comment from many cairo_runner tests
