Store constants in Hint Data

[JulianGCalderon]

In some situations, we have a top-level Cairo program that itself executes other Cairo programs.

The Cairo Runner is being initialized with the top-level program. This means that, when executing hint, the constants passed to the hint belong to the top-level program. If the inner programs has hints that depends on constants defined only in the inner program, then the execution would fail as the constants are being searched in the top-level program's constants, and not in the inner program's constants.

This PR fixes this by having the constants specified on compile_hint, rather than on execute_hint. When compiling a hint for the inner program, we can specify the constants of that inner program.

Breaking Changes

This PR introduces breaking changes:

• The signature of the HintProcessor methods changed. We now specify constants on compile_hint, rather than on execute_hint.
• The CairoRunner::step_hint method no longer receives the program constants, as they no longer require it.
• The CairoRunner::step method only receives constants when the test-utils features is enabled, as its used for the pre/post step hooks.
