Clemens Hammacher 07752032e6 [wasm] Decode local names for debugging 
When providing scope information (containing the value of local
variables of live stack frames), decode the local variable names of all
functions in a wasm module and store this in the WasmDebugInfo
structure.
Use these names to actually name the reported locals, instead of using
the default names "param#<d>" and "local#<d>". These names are only used
as fallbacks for locals which were not assigned a name.
