Johnni Winther 90ec6f2531 [cfe] Ensure that shorting is stopped before expression usage
The creation of the shorting stop expression was done lazily
in NullAwareExpressionInferenceResult.expression. Since the shorting
calls flow analysis to stop null promotion doing this out of order
let to inconsistent flow analysis state.

This CL introduces an `inferNullAwareExpression` the allows to
caller to continue the shorting (if in an opt-in library). The
inferExpression method, used everywhere else, stops any shorting
currently in progress.

Closes #43275

FE/analyzer shared code

This package contains logic that is shared between the front_end and analyzer packages. It is intended solely to facilitate development of the Dart SDK, and is not intended for use by end users. In particular, this package has no public API, so no guarantee is made of compatibility between one version of the package and the next.

End users should consider using the analyzer package to analyze Dart source code.
