[FR] add orderfile creation script to the NDK

### Description

Order files require some processing before they're consumed by lld (why? could we just upstream whatever the script is doing into lld?): https://android.googlesource.com/toolchain/pgo-profiles/+/refs/heads/main/scripts/create_orderfile.py. We should include that script in the NDK.

Start by reading the referenced create_orderfile.py script and inspect the NDK's packaging or build entry points to find where utility scripts are included. Determine how this script should be shipped and invoked within the NDK, then verify that the packaged NDK contains it and that its intended order-file workflow remains usable.
