* support feature flag service in IExperimentationService

this will let us to create private ring of specific groups for new features until it is ready for bigger group.

once feature is ready for bigger group, this service can support VS experiment flight service which will let us to enable new features for bigger group.

once we are confident on the feature, we will enable it for general public

* remove extra blank line

Introduce a new 'wrap binary expression' (without alignment) refactoring.

Add helpers to make it easy to compute smart-indenting in wrapping refactoring.

* Improve the error message for an 'in' extension method so it's clear why constraining it to a struct wont help.

* Eliminate unspeakable NullableAnnotation values.
* Dynamic invocations result in an oblivious state
Fixes #33638
* Fix up expected diagnostics
Due to #33924
* Rename NullableAnnotation.Unknown to NullableAnnotation.Oblivious

Simplify error code comparison

Code style change based on review.

Defensively call ErrorFacts.PreventsSuccessfulDelegateConversion(xCode), and explain why in a comment.

Move to BYOC pools

Add MakeStatementAsynchronous fixer

Fixes #33905

This changes our pipelines to use the BYOC (Bring Your Own Cloud) pools
hosed by the core engineering team. This is a dynamic queue which should
scale better for our uses than the static pools we are using today.

Test handling of a small selection of lifted built-in unary and binary operators

Enable roll forward in our .NET Core exes

Restore fluent call depth

Remove call to ErrorFacts.PreventsSuccessfulDelegateConversion(xCode), since no longer necessary, and not necessarily an optimisation

This changes our build to mark all of our .NET Core applications as
rolling forward on major / minor versions of the .NET framework.
Presently our tools ship inside both .NET Core 2 and 3 SDKs. This
setting allows our tools to run unmodified in both settings.

closes #25606

The change to move nullable to a two state solution inadverntently
changed how the CLR inlines a number of method calls. The combination of
not-inlining and over-inlining caused us to have a much larger "frame"
for analyzing a fluent call and exceeded our tolerance levels.

This adjusts the inlining so that we get the same results as before.

closes #33775
