Measure only mobile package files in SOD jobs

[matouskozak]

Summary

• stage only the signed APK/IPA and versions.json for mobile package-size SOD work items
• extract only Payload from the IPA so iOS extracted size measures the installed app bundle
• exclude binlogs, dSYMs, mapping files, unsigned APKs, and resource-designer assemblies from app-size metrics

Metric changes

APK Size / IPA Size now report exactly one file — the distributable package.

Extracted Size now reports only package contents. On iOS this also drops Apple's top-level Symbols directory, which the .NET iOS SDK adds to the IPA via _CreateIpaSymbols for crash symbolication but which is not part of the installed app. It accounted for 40–72% of the previous iOS extracted totals, so expect a one-time step down in that series. Android extracts APK contents only and is unaffected by that scoping.

This aligns with how the MAUI performance investigation repo measures app size: signed APK bytes on Android, .app bundle on iOS.

Validation

• xmllint --noout eng/performance/maui_scenarios_android.proj eng/performance/maui_scenarios_ios.proj
• git diff --check
• verified locally against a real archive that unzip -d <dir> <ipa> 'Payload/*' extracts the app bundle and excludes Symbols
• internal perf build 3030421 covered the staging change
  • all four Android Galaxy SOD-bearing jobs and all four iOS jobs succeeded
  • all 31 APK/IPA metrics reported exactly one file
  • Android package bytes matched the signed APK from the main comparison build exactly; iOS package drift was at most 546 bytes (0.0021%)
  • the only failed mobile job was an unrelated Pixel NoAnimation startup job, where SOD is disabled
• internal perf build 3032474 covered the iOS extraction scoping
  • all 16 iOS SOD work items exited 0; every extracted-size result contains zero non-Payload files
  • all 16 extracted totals match the Payload-only subset of build 3030421 byte-for-byte, confirming only Symbols was dropped
  • the NativeAOT iOS job is marked failed because its Helix wait step hung for two hours after all 16 work items had already finished successfully, then hit the job timeout; this is a Helix polling issue unrelated to this change

Pull request overview

This PR updates MAUI mobile SizeOnDisk (SOD) Helix work items so that app-size metrics measure only the actual package artifacts (signed APK/IPA) plus versions.json, instead of recursively measuring an entire publish directory that may contain unrelated build outputs.

Changes:

• Android SOD work items now stage only the signed APK and versions.json into pub (instead of copying the whole scenario directory).
• iOS SOD work items now stage only the IPA and versions.json into pub, and unpack only the staged IPA for extracted-size measurements.
