-----------
[stable] [ dart:io ] Fix bad type casts in network_profiling.dart

Issue description: In 32e45cf30031dd2466eaedbf5d98c457eff1bb61, types were updated from
Map<String, dynamic> to Map<String, Object> in some situations. These
two aren't compatible and can lead to runtime type cast failures.
What is the fix: update changes from Map<String, Object> to Map<String,
Object?>
Why cherry-pick: this can cause network profiling to stop working
seemingly randomly in DevTools.
Risk: Low, tests added to verify original behavior and validate fix

CoreLibraryReviewExempt: Only internal dart:io details.
