Add support for adapter-specific parameters

[armalikhani]

This PR introduces support for adapter-specific configuration parameters by restructuring how adapter and backend settings are defined and consumed.

The goal is to allow users to directly define adapter-specific runtime configurations (such as no_modify or queued arguments for the MQSS Qiskit adapter). This improves modularity and makes the configuration system more extensible for future adapters.

Changes

• Introduced adapter_params as a unified top-level configuration section for adapter-specific settings
• Added backend_params for adapter-specific backend configuration
  • Supports mqss_qiskit and qiskit_simulator adapters
• Moved existing adapter fields (backend, credentials, shots) under adapter_params
• Refactored BenchmarkRunner and DeviceAdapter implementations to use the new structure
• Updated tests, examples, and README
• Limit adapter circuit printing to verbose mode for cleaner batch run logs

Breaking Changes

This change introduces a breaking change in the configuration schema.

• Top-level fields backend, credentials, and shots have been removed
• These fields must now be defined under adapter_params

Example:

adapter_params:
  backend: ...
  backend_params:
    ...
  credentials: ...
  shots: ...
