1663 i09 energy

[Relm-Arrowny]

Fixes #1663

• Implemented J09EnergyMotorLookup to enable energy lookup for the i09-2 ID (Insertion Device).
• Introduced J09Apple2Controller to manage Apple II polarization and the conversion of energy to motor movement.
• Refactored test setup by adding conftest.py to both i10 and i09_2_share folder to reuse fixtures.
• Updated the i09_2 configuration to include devices for beam energy, ID energy, and polarization.

Instructions to reviewer on how to test:

1. Do thing x
2. Confirm thing y happens

Checks for reviewer

• Would the PR title make sense to a scientist on a set of release notes
• If a new device has been added does it follow the standards
• If changing the API for a pre-existing device, ensure that any beamlines using this device have updated their Bluesky plans accordingly
• Have the connection tests for the relevant beamline(s) been run via dodal connect ${BEAMLINE}
