feat: Make MAX_NET_DETUNING in AHS device capabilities optional and extend field validator utility functions.

[Altanali]

Issue #, if available:

Description of changes: Make the MAX_NET_DETUNING device capability data point optional for AHS program validation - this is done so the Program validator used for AHS programs with the local simulator can also be used with capabilities derived from QPU capabilities, which don't provide a MAX_NET_DETUNING data point.

Additionally, utility methods validate_max_absolute_slope,validate_time_precision,validate_time_separation,validate_value_precision are added to field validator utilities for use AHS Program validation with Device Capabilities Constants (introduced in BDK).

Testing done: Tested the newly introduced field validation utility functions.
