General improvements to Linux story

Fix flaky compiler server test

Optimize ArrayBuilder<T>.ToImmutableAndFree

Reduce the number of attributes that should be bound in order to determine if there are NoPia local types explicitly defined in code. (#23505)

Fixes #23179.

Add VBCSCompiler.dll to the Microsoft.NETCore.Compilers package

Perform a lightweight syntax check before getting document options

* Refactored synthesized attributes tests

* Remove rest of calls to CompilationUtils.GetSynthesizedAttributes()

* Fix EE tests

* Fix [Dynamic] tests

* Clean up

* Remove EmitMetadataTestBase.ValidateDeclSecurity(Compilation)

* Remove C# GetDefaultPEBuilder

* Fix Assembly Attributes tests

* Clean up

* Address PR Comments

* Clean up

previously, we set all work as done when we pass out last work from the queue without waiting that work to be done.

now, we raise works as done only when last item passed out are actually done.

Mark Toolset projects non-shipping

Use TryDequeue before falling back to DequeueAsync

Keep compilation alive in GetPartialSemanticModelAsync

Avoid TryReplaceWithAlias logic for documents without using alias directives

Reduce allocations in DeclarationTable.RootNamespaceLocationComparer.Compare

As with InternalToolset, we don't want to bother restoring the
xliff-tasks package for this project.

Mark InternalToolset.csproj as non-shipping. This prevents the project
from pulling in a `PackageReference` to xliff-tasks, which it doesn't
need and, more to the point, can't be found in the NuGet feeds used when
the project is restored.

* Use GetOriginalSemanticModel instead of duplicating logic
* Move local function to separate helper method

Avoid an O(n²) array expansion in BuildDeclarationCompilationFromScratchAsync

Avoid a capturing local variables on the GetOptionsAsync fast path

Enable Microsoft.CodeAnalysis.VisualBasic.UnitTests.GetExtendedSemanticInfoTests.GroupBy_Lookup1 unit-test. (#23600)

Closes #23483.

Fixes #23378.
Also, preserve and adjust arguments passed to 'new T'.

Enable the production of localized resources (e.g. satellite assemblies) out of the dotnet/roslyn repo.

This includes the tooling and initial (untranslated) .xlf files, but does not consume the satellite assemblies in any way. Once the Loc team has had a chance to update the files with proper translations we will work on putting the satellite assemblies into our NuGet and Willow packages.

Don't include any satellite assemblies in
Roslyn.Compilers.Extension.vsix. We're currently generating satellite
assemblies, but until the loc team has had a chance to update the .xlf
files the contents of the satellite assemblies will be wrong.

Update Microsoft.DiaSymReader.Native to 1.7.0 stable

Currently some but not all of the Samples projects are marked `<NonShipping>true</NonShipping>`, though we don't actually ship binaries for any of them. This commit marks them all as non-shipping, which stops the build from trying to build localized resources unnecessarily.
