## Proposed changes
The master378 publish timer reset timestamps for already-ready
subscriptions, breaking oldest-first ordering among equal-priority
subscriptions.
- Restore the ready-subscription guard.
- Recheck readiness under the queue lock to prevent concurrent timestamp
resets.
- Replace invalid requeue coverage with a deterministic ordering
regression test.

This change adds a **new Opc.Ua.Types** nuget that contains core types that do not rely on generated code. Why the name? Because almost all code that was in the Types subfolder is part of it, and because we do not want to change the name of the Opc.Ua.Core nuget/assembly because code relies on it. Any other name like base or bootstrap felt out of place due to the current structure already defining the name "types". Key design is to depend on only a small set of libraries with limited transitive dependencies, that includes hashcode, logging.abstraction, and for non standard20 builds System.Text.Json (needed for localizedText mul parsing). Also, key is to support .netstd 2.0 to support source generators and to allow removal of EEC_SUPPORT defines by removing std2.0 from core and all libraries.
The changes are mostly restructuring, and thus small but contain some key changes:
- **Status code** struct now comes with a Symbol field, which is used to carry symbols in case the code is not generated. Currently (until generated) the status code struct must be manually created with a symbol or the ToSymbolicId extension must be called in the core project. Future will generate Status code constants just like NodeId that contain the symbol which also removes the reflection-based lookup. Several tests needed to be adjusted as they checked the status code symbol strings instead of the code.
- **Core identifiers** are copied as they were needed for code to compile, that includes attributes, a subset of status codes and node identifiers. These will never change so no need to generate them.
- The types folder now contains **encoders**, except for json which is still in core. Once the json encoder is ported to system.text.json it will also be included and Newtonsoft.Json dropped as dependency (-> #3329).
- Since types relies on **IOperationContext** and **ISystemContext**, and these export IUserIdentity which relies on crypto, these were split and extended in core with ISessionOperationContext and ISessionSystemContext, which mean changes to ServerSystemContext and introduction of SessionOperationContext and SessionSystemContext classes that extend OperationContext and SystemContext. Some runtime checks in the server are therefore needed to get at the session and auth info, however, those are anyway optional fields and are not on the critical paths, and thus a type check is in order (and was done in the past already, but against OperationContext class).
- **Manifest resources** are now split between Core (nodeset zip, some generated resoures) and Types (built in bsd/xsds). This needs to be revisited later if the bsd/xsd need to be regenerated during type generation. Note that the embedded resource names changed as a result. Since these are only used internally and do not constitute public API this feels reasonable vs duplication of resources in 2 assemblies.
- Reflection however now needs to load not just the built in **encodeables** from Opc.Ua.Types assembly, but also the generated encodeables from Opc.Ua.Core assembly. For this a new helper Utils method was added to get the Core assembly when linked against Opc.Ua.Core otherwise null.
- Whatever utils methods needed to be split out into the new Opc.Ua.Types assembly, they are now in **CoreUtils** static class in Opc.Ua.Types, and Utils.xxxx forwards to them to ensure minimal changes. Later we would want to obsolete them in favor of CoreUtils, although it might make sense to split them again into domain specific utilities, such as networking, files, etc

The goal is to reduce the overall number of builds, stop using end of life platforms in the build pipeline and to support
build of future/deprecated build targets in a custom build step, which is also triggered weekly in the ci builds.
In addition:
- added a doc which describes the release and versioning strategy of this project
- produce the Nuget packges with .NET 8 assemblies.
- produce a Docker build based on a .NET 8 based container.
- add custom test targets to test outdated platforms. Need a manual step to enable for VS or command line.
- bug fixes: the latest move to an alternate crypto library for Bouncy Castle, which is only used for the GDS support and .NET Framework 4.6.2./netstandard2.0, revealed already a few issues which were previously not found.
- only .NET8/.NET6/.NET Framework 4.8 are tested in Pull requests. Remaining builds in weekly scheduled builds.
- Deprecate support for Nuget package support of .NET Framework 4.6.2
- Bump sample applications to 4.8
- update some copyright headers / supporting files (editorconfig etc.)
- fix a few warnings
- fix an issue with `SessionReconnectHandler`, in certain combination of reconnect period and exponential backoff the .NET sample app never reconnected.
* Bump BenchmarkDotNet from 0.13.2 to 0.13.3
* Bump Moq from 4.18.3 to 4.18.4
