LibJS: Get rid of unnecessary work from canonical_numeric_index_string

Browse source 
The spec version of canonical_numeric_index_string is absurdly complex,
and ends up converting from a string to a number, and then back again
which is both slow and also requires a few allocations and a string
compare.

Instead lets use the logic we already have as that is much more
efficient.

This improves performance of all non-numeric property names.
