Add .NET 10 (preview) as the default TFM and enable multi-targeting builds (#949)

* Initial plan

* Add .NET 10 (preview) as a TFM for multi-targeting builds

Co-authored-by: aaronpowell <434140+aaronpowell@users.noreply.github.com>

* Change default TFM to .NET 10 and update GitHub Actions to install .NET 10

Co-authored-by: aaronpowell <434140+aaronpowell@users.noreply.github.com>

* Update devcontainer to install .NET 10 as preview

Co-authored-by: aaronpowell <434140+aaronpowell@users.noreply.github.com>

* Add .NET 10 to setup-runtimes-caching action

Co-authored-by: aaronpowell <434140+aaronpowell@users.noreply.github.com>

* Fixing some versioning

* Hard coding an update to use Apache.NMS.AMQP@2.4.0 as 2.2.0 has a CVE but the MassTransit.ActiveMQ package isn't updated yet

Tracked: MassTransit/MassTransit#6133

* Fixing some projects that specified their own TFM and trying to address ambiguous referencing

* Using an improved approach approach to adding system.linq.asyncenumerable

* Updating how dev certs are setup

* Turns out you can't upgrade around the CVE, so we now suppress it

I feel dirty doing that...

* skipping tests which would do nothing

* Some msbuild library updates

* handling .net 8 down leveling of packages

* Removing .NET 10 support from sql database projects integration

* test and example projects set to net8.0

* Setting target frameworks too

* Moving to the new sdk structure

* how'd I miss that merge

* Can't have Aspire.Hosting.AppHost in CPM as it's implicitly added

* Back to zero compiler errors, woo

* Removing the .net down levelling there too

* Missed another reference to the apphost package

* reverting a change

* Attempting to force the removal of some nuget packages that we don't want at runtime

* csproj mistake

* Going nuclear on the files in a post-build task
