Disable analyzers on developer builds

Use ConfigureAwait

Restructure how assets are published

A recent change to enable analyzers caused a 3-6X build slow down.
Disabling them locally at least until we can track this down.

Be resilient to getting back no spans to tag.

[Test failure] BasicExpressionEvaluator: COMException : Operation not supported. Unknown error: 0x8971003c  (#21037)

In integration tests, verify that we send telemetry

Re-enable analyzers in the master branch

Fix crash with F# project references

Move to newer version of Microsoft.Net.Compilers and Microsoft.NetCore.Compilers compatible with latest analyzers package

If you had a F# project opened with the new project system, it'd supply
an output directory which other projects (like C#) could reference.
If you had a C# project that referenced the F# project, any attempt
to get the C# compilation would crash because we can't actually produce
F# compilations. The fix is simple: don't convert from metadata
references.

If we're going to require it, let's at least crash with a useful
exception instead of a null ref.

Other components should be able to access this too, especially since
the workspace itself isn't always there.

Preserve leading directives when removing an unused variable.
