Fix nuget package generation

* Add support for binary user properties in MQTT 5.0

* Optimize byte array reversal in SubscriptionTopicHashTests

* Use InvariantCulture for topic string conversion in Load_Tests

* switched to `Microsoft.Testing.Platform`

* Refactor CI workflow to separate signed and unsigned package builds

* Add condition to sign job to prevent execution on external pull requests

* Remove fallback to value as string in MqttUserProperty

* Refactor MqttUserProperty handling to use byte arrays for improved performance and add deprecation warnings for legacy methods

+### Verification
+
+Before opening a bug make sure that the following conditions are met.
+<!-- Remove this chapter when all conditions are met. -->
+
+1. Performance issues are also appearing in RELEASE mode of your application.
+2. An increased memory consumption or high CPU load also happens when your application runs in RELEASE mode AND logging is DISABLED.
+3. Client issues with not received messages, connection drops etc. can be reproduced via another client application like "MQTTnetApp" (https://github.com/chkr1011/MQTTnetApp) or similar.
+4. The bug also appears in the VERY LATEST version of this library. There is no support for older version (due to limited resources) but pull requests for older versions are welcome.
+
+### Describe the bug
+A clear and concise description of what the bug is.
+
+### Which component is your bug related to?
+<!-- Remove the items which don't apply from the following list. -->
+- Client

+
+### To Reproduce
+Steps to reproduce the behavior:
+1. Using this version of MQTTnet '...'.
+2. Run this code '....'.
+3. With these arguments '....'.
+4. See error.
+
+### Expected behavior
+A clear and concise description of what you expected to happen.
