refactor(shared-data): Rename labwareSchemaShims.ts -> positionMath.ts (#18888)

This file has grown to hold more than just simple compatibility shims
for converting between labware schemas 2 and 3. It now also holds actual
business-domain math for computing labware and module positions. Rename
it accordingly.
