Increase timeout to 90min for ARM64-Xcode16-targeting-iphonesimulator (#24091)
### Description
<!-- Describe your changes. -->
There are still some timeout for the pipeline. further extend the
timeout to 90 minutes for ARM64-Xcode16-targeting-iphonesimulator.
It takes quite a while if all build cache is missing.
### Motivation and Context
The pipeline sometimes failed because of timeout. There is a previous PR
#24030 to increase the timeout from 60min to 75 min but it looks like
not enough.
