[JVM IR] Do not put destructuring params or underscores in LVT.

Putting them in the local variable table means that the debugger
needs to have special handling for parameters with specific names.
That forces us to generate mangled names for these.

Instead of also implementing the name mangling for FIR, this
change gets rid of the parameters from the LVT instead.
