[sdk] Mark dart:developer APIs with since information

Without the since information added, packages can use these APIs despite their SDK constraints potentially allowing SDK versions without them. For example, in package:leak_tracker recently: https://github.com/dart-lang/leak_tracker/issues/201.

I only added Since information to APIs added since Dart 2.12 since that's the lowest relevant SDK constraint with sound null safety.

TEST=ci

Cq-Include-Trybots: luci.dart.try:flutter-analyze-try
CoreLibraryReviewExempt: This CL does not change any APIs or their implementation, only adding relevant Since documentation to support correct triggering of the sdk_version_since diagnostic.
