Description

Prepack should try to keep original variable/function names whenever possible, instead of producing ids such as _123. Prepack already has a debugNames flag that appends the original names using some name mangling convention. However, it would be nice if the exact original names could be kept whenever possible.

Research direction
Start by exploring how Prepack currently handles variable/function name mangling, particularly the debugNames flag in the serializer source code. Understand the existing naming convention and the serialization pipeline. Then, design a way to preserve original names when possible, avoiding naming collisions. Review the serialization output module to implement the change.
