Registry memory leak fixes.

Registry memory leak fixes.

Fixes #24549.

A few notes:
  * does away with registry in favor of context-associated configurations
  * pulls in linter rev that does the context association
  * bumps analyzer version before publishing (needed to update analyzer_cli)

File pkg/analyzer/lib/src/services/lint.dart (right):

pkg/analyzer/lib/src/services/lint.dart:49: static const List<Linter> _noLints =
const <Linter>[];
The rest of the code base generally defines constants like this in the class of
the element type (Linter in this case). Might be good to be consistent.
