/**
* Assigns all attribute values to the provided element via the inferred renderer.
*
* This function accepts two forms of attribute entries:
*
* default: (key, value):
* attrs = [key1, value1, key2, value2]
*
* namespaced: (NAMESPACE_MARKER, uri, name, value)
* attrs = [NAMESPACE_MARKER, uri, name, value, NAMESPACE_MARKER, uri, name, value]
*
* The `attrs` array can contain a mix of both the default and namespaced entries.
* The "default" values are set without a marker, but if the function comes across
* a marker value then it will attempt to set a namespaced value. If the marker is
* not of a namespaced value then the function will quit and return the index value
* where it stopped during the iteration of the attrs array.
*
* See [AttributeMarker] to understand what the namespace marker value is.
*
* Note that this instruction does not support assigning style and class values to
* an element. See `elementStart` and `elementHostAttrs` to learn how styling values
* are applied to an element.
* @param renderer The renderer to be used
* @param native The element that the attributes will be assigned to
* @param attrs The attribute array of values that will be assigned to the element
* @returns the index value that was last accessed in the attributes array
