Final pre-publish housekeeping

[craiglabenz]

• Removed dependency on Flutter from packages - all are now pure-Dart
  • Various linting changes (removing redundant null-check operators) that emerged by moving from flutter_lints to lints
• Moved dependencies on mediapipe_core to 0.0.1 (already published)
• Added supported platforms declaration
• Added MediaPipe's license files

A few more to fix:

Odd that my editor didn't tell me about those... 🤔

It turns out I hadn't run dart pub get since bumping the SDK requirements above 3.2, which is when private field promotion arrived.

As far as I can tell, these latest integration test failures are a false-positive. They passed until recently in CI and still pass locally.

DBC: If I'm not mistaken the list of flutter lints is bigger than the lints package. So you might as well keep flutter_lints if you don't mind satisfying them. It makes the code more pleasant to read to typical flutter users. (And flutter_lints doesn't require a flutter SDK.)

Now that's a hot tip!

Merging as test failures are false positives from dart-lang/sdk#55712
