Add ability for frequency override in gate operations

Explanation of changes

1. Add ability to override the frequency for some operations.

Measure(qubit="q0", freq=5e9)

2. Add ability to "reset" the frequency to the clock frequency using the SetClockFrequency operation: SetClockFrequency(clock=clock, clock_freq_new=None). This resets the frequency to the frequency set in the configuration or the clock device element.

Motivation of changes

There is already a way to override device-level parameters for gate-operations. Additionally, we sometimes need to override frequencies for some operations, for example when we sweep measurement operations for frequency sweeps.

Merge checklist

See also merge request guidelines

• Merge request has been reviewed (in-depth by a knowledgeable contributor), and is approved by a project maintainer.
• New code is covered by unit tests (or N/A).
• New code is documented and docstrings use numpydoc format (or N/A).
• New functionality: considered making private instead of extending public API (or N/A).
• Public API changed: added @deprecated and entry in deprecated code suggestions (or N/A).
• Newly added/adjusted documentation and docstrings render properly (or N/A).
• Pipeline fix or dependency update: post in #software-for-developers channel to merge main back in or update local packages (or N/A).
• Tested on hardware (or N/A).
• CHANGELOG.md and AUTHORS.md have been updated (or N/A).
• Update Hardware backends documentation if backend interface change or N/A
• Check whether performance is significantly affected by looking at the Performance metrics results.
• Windows tests in CI pipeline pass (manually triggered by maintainers before merging).
  • Maintainers do not hit Auto-merge, we need to actively check as manual tests do not block pipeline
