CSS modules were used as a first test for performance optimization.
We later found out that Linaria was a better tradeoff.
This PR removes what was implemented in CSS modules and also the CSS
theme file that was created that was overlapping with the TS theme
files.
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
