Selectable Tipracks: Add the ability to select a tiprack for pipette offset calibration

[sfoster1]

Using the data in #7085 and the components in #7086, implement the ability to select a tiprack for pipette offset. This selection does not have to be saved.

The selection should

• Default to the tiprack used in pipette offset calibration, if there is one
• Default to the "preferred tiprack" for the pipette in Selectable Tipracks: Add tiprack preferences to namespecs #7085 if there is no pipette offset calibration
• Be independent of what, if any, tip length calibrations exist. Selecting a tiprack that does not have a tip length calibration should force the session into calibrating the tip length.
• Display all available tipracks from Selectable Tipracks: Add tiprack preferences to namespecs #7085 with appropriate illustrations if available
• Also display all tiprack-tagged custom labware without volume filtering

This ability should only be allowed from the pipette-offset-calibration intent, i.e. a user calibrating a pipette during attach; clicking calibrate offset in the instrument settings panel; or clicking recalibrate offset. For the tip length intents, this should not be displayed, since the tip rack to use is implied.
