[vm/kernel/aot] Approximate numerous invocations per selector in TFA

This change adds tracking of number of invocations with the same
selector but different arguments. If this number reaches certain limit,
all subsequent invocations with such selector are approximated.

On Flutter gallery, 1 selector is approximated:
  dart.core::Object::==

On Analyzer, 2 selectors are approximated:

  analyzer.dart.ast.ast::AstNode::visitChildren
  dart.core::List::[]=

Flutter gallery Total(CodeSize): +11 K.

Fixes https://github.com/dart-lang/sdk/issues/33199
