Remove usage of 'required reason' iOS API from protobuf (#20529)

### Description
<!-- Describe your changes. -->

Using certain APIs is about to require a [privacy
manifest](https://developer.apple.com/documentation/bundleresources/privacy_manifest_files/describing_use_of_required_reason_api)
to be added to a package.

Our version of protobuf uses `mach_absolute_time`. Patch as per
protocolbuffers/protobuf#15662 to remove usage.

### Motivation and Context
<!-- - Why is this change required? What problem does it solve?
- If it fixes an open issue, please link to the issue here. -->
Usage of API will require a privacy manifest for an iOS app to be
accepted as of 5/1/2024
