Implement module and local names in name section (#3115)

Adds support for the module and local subsections of the name section plus the respective C and JS APIs to populate and obtain local names.

C API:
* BinaryenFunctionGetNumLocals(func)
* BinaryenFunctionHasLocalName(func, index)
* BinaryenFunctionGetLocalName(func, index)
* BinaryenFunctionSetLocalName(func, index, name)

JS API:
* Function.getNumLocals(func)
* Function.hasLocalName(func, index)
* Function.getLocalName(func, index)
* Function.setLocalName(func, index, name)
