Auto merge of #9786 - peterjoel:fix_codegen_is_array_like, r=jdm

Browse source 
Fixed compile error in generated code, when webidl constructors have same number of args

One of the ways that generated code differentiates constructors is by comparing if the args are array-like. The generated code was calling a function `IsArrayLike` that no longer exists. I re-implemented it with a more rust-like naming scheme.
