.Net: [MEVD] Stop using trimming-incompatible JSON serialization

[roji]

MEVD provider implementations make frequent use of JsonSerializer.SerializeToNode() in various ways which are NativeAOT-incompatible. Examples include in mappers (e.g. in WeaviateDynamicMapper), when processing

To work on this, simply drop the following in a provider's csproj:

<IsAotCompatible Condition="$([MSBuild]::IsTargetFrameworkCompatible('$(TargetFramework)', 'net8.0'))">true</IsAotCompatible>

This will start generating NativeAOT- and trimming-related warnings. Once this is done, it should be possible to remove [RequiresUnreferenceCode] and [RequiresDynamicCode] from the provider's dynamic collection constructor and to build without any warnings.
