Run a curated NativeAOT subset on Apple-mobile extra-platforms

The full library set (~150 projects) does not fit in 240-minute AzDO
budget on iossimulator/maccatalyst/tvos NativeAOT (Build product:
ILC + Xcode link/bundle per project times out repeatedly).

- runtime.yml NativeAOT_Smoke legs keep /p:RunSmokeTestsOnly=true and
  run System.Runtime.Tests + iOS functional tests.
- extra-platforms NativeAOT legs drop /p:RunSmokeTestsOnly=true and
  use a new explicit ProjectReference list in src/libraries/tests.proj
  (gated on TargetsAppleMobile && UseNativeAOTRuntime) which references
  9 representative library tests (Runtime, Collections, Linq, Threading,
  Threading.Tasks, IO.FileSystem, RegularExpressions, Text.Json,
  Net.Http) instead of the wildcard. Timeout reverted to 180 minutes.
