Feat/performance-refactor-styled-component (#5516)

In this PR I'm optimizing a whole RecordTableCell in real conditions
with a complex RelationFieldDisplay component :
- Broke down getObjectRecordIdentifier into multiple utils
- Precompute memoized function for getting chip data per field with
useRecordChipDataGenerator()
- Refactored RelationFieldDisplay
- Use CSS modules where performance is needed instead of styled
components
- Create a CSS theme with global CSS variables to be used by CSS modules
