RFR: 8175874: Update Security.insertProviderAt to specify behavior when requested position is out of range. [v7]

[Ben Perez]

> Fixing the bug as stated would cause compatibility issues. E.g. the `addProvider` function always adds new providers at position 0 and therefore would always throw an error. Instead of changing how the function handles indices, we instead have added this behavior to the function spec.
