Use more specific panic message for &str slicing errors

Separate out of bounds errors from character boundary errors, and print
more details for character boundary errors.

Example:

    &"abcαβγ"[..4]

    thread 'str::test_slice_fail_boundary_1' panicked at 'byte index 4 is not
    a char boundary; it is inside `α` (bytes 3..5) of `abcαβγ`'
