bazel syntax: eliminate unnecessary array copying Before, EvalUtils.toCollection would return a view (if given a Sequence) but a copy if given a Dict. This makes it inefficient and also hard to reason about. This change replaces it with Starlark.toIterable and Starlark.toArray: the first always returns a view, the second a copy. Also: - CallUtils: eliminate array copying in handling of *args and **kwargs. - Start removing Location parameters from everything we touch. Location is automatically added to EvalExceptions by the interpreter. - MethodLibrary: eliminate array copies in sorted, reverse, tuple, list, enumerate. - Also in string.join, string.partition. Simplify the latter function. - Improve text of an error message. - Declare Starlark.len, which returns the length of a string or iterable. This change removes support for Starlark Map other than Dict, because there are none today. PiperOrigin-RevId: 282682290
