feat: `usort` hints integration tests

[TAdev0]

@cicr99 i checked hints separately locally and it seems fine, except usortBodyCode which is not detected by our VM, just like signedDivRem

We might need to do like lambda go and declare each hint as a const

Usort integration test is finished. I modified a few things in usort hints:

• There was fp.Element used in 2 places where uint64 should have been used. It saves some computation moreover
• I hardcoded usort_max_size which is a global(), just like we did for keccak state size or keccak max input size
• I reorder all the usort hints so that they are in the order they are executed in usort cairo function

Let's wait Finalize Segment to be merged to make sure the memory traces match, but i tested outputs and everything against other VMs and its ok

@har777 @cicr99 @MaksymMalicki ready for approval/merging

I added a new test for it to make sure multiplicities works well (lambdaclass didnt cover this)

@Sh0g0-1758 we already discussed with Carmen the change to uint64 here. If you check in detail, you'll see i changed it always for variable that represents either a length of array or a index in an array. Its ok then
