Extend timeout of libs legs in nativeaot-outerloop

[MichalStrehovsky]

Product & test build takes around 3 hours. If Helix is backed up enough, it can take 2+ hours to process these workitems. Clicking through the past few outerloop runs, this is the number 1 reason when they're red.

Code Review: Extend timeout of libs legs in nativeaot-outerloop

Summary

This PR increases timeoutInMinutes from 300 (5 hours) to 360 (6 hours) for three NativeAOT library test legs in the outerloop pipeline:

• NativeAOT_Libs
• NativeAOT_Checked_Libs_SizeOpt
• NativeAOT_Checked_Libs_SpeedOpt

Analysis

Category	Assessment
Correctness	✅ No issues — the change is a straightforward numeric constant bump applied consistently to all three affected jobs.
Consistency	✅ All three lib legs are updated to the same value.
Risk	✅ Extremely low — only affects CI timeout thresholds, no product code changes.

The existing comment ("doesn't normally take this long, but I've seen Helix queues backed up for 160 minutes") remains accurate — the extra hour of headroom is a reasonable buffer given the described 3-hour build + 2+ hour Helix queue scenario.

Verdict

APPROVED — no issues found. The change is minimal, well-motivated, and correctly applied to all relevant jobs.
