FIR: Rework FirRegularTowerDataContexts

- Get rid of SPECIAL mode (just left REGULAR and class-related instead)
- Clear naming
- Restore contexts after lambda/callable reference are processed

The test has been failing before this change because after
callable reference is resolved, its tower data context has been left
erroneously in the SPECIAL-related entry
