LibJS: Replace m_functions_to_initialize with pre-created data

Browse Source 
Replace Vector<FunctionDeclaration const&> with a FunctionToInitialize
struct that stores a pre-created SharedFunctionInstanceData, function
name, and local index. The SharedFunctionInstanceData for each hoisted
function is created eagerly during the parent's construction, removing
the need to reference FunctionDeclaration AST nodes after construction.
