## Summary

Fixes #5618 

The generated LIN/SCI headers have some misnamed interrupt macros.

`CLEARINTLVL` bit 8 was auto-generated with a generic name:

```c
TMS570_LIN_CLEARINTLVL_8
TMS570_SCI_CLEARINTLVL_8
```

This MR updates them to semantic TX interrupt level clear names:  
`TMS570_LIN_CLEARINTLVL_CLR_TX_INT_LVL`  
`TMS570_SCI_CLEARINTLVL_CLR_TX_INT_LVL`  

Bit 25 is the overrun-error interrupt bit, but some macros used `CE` instead of `OE`.  
This updates to use `OE` consistently.  

Also removes the duplicated `*_CLEARINTLVL_CLR_CE_INT_LVL` definition in both headers.

Tested on TMS570LC4357 LaunchPad XL and validated.
