LibJS: Replace VariableNameToInitialize with value-type VarBinding

Browse Source 
Replace VariableNameToInitialize (which holds Identifier const&) with a
VarBinding struct that stores pre-extracted values: name, local index,
parameter_binding, and function_name. This removes a reference to AST
Identifier nodes from SharedFunctionInstanceData, allowing the AST to
be freed after compilation.
