[sldev] [VWR] LSL Compiler Limitations?

[Phoenix]

The build team here continues to use lex and yacc and the process to  
strip out things we cannot redistribute swaps around a few uuids and  
filenames to switch it over to flex and bison.

SL-45464: Fix lex-compiler issue causing a hard limit in the number  
of script parameters

is marked as resolved, but obviously something is wrong. I will  
investigate.
