Move `InsnBitWidth` template into anonymous namespace in the generated code and move template specialization of `InsnBitWidth` to anonymous namespace as well, and drop `static` for them. This makes `InsnBitWidth` completely private to each target and fixes the "explicit specialization cannot have a storage class" warning as well as any potential linker errors if `InsnBitWidth` is kept in the `llvm::MCD` namespace.
