adds virtual thread support for activity execution context

[TbirdDuncan]

updates CurrentActivityExecutionContext.java to support that mission
adds test for CurrentActivityExecutionContextTest
removed unused code in temporal-sdk/src/test/java/io/temporal/internal/nexus/WorkflowRunTokenTest.java

What was changed

The activity execution context is now usable within virtual threads

Why?

I was working a temporal project, and went to make use of virtual threads. I noted that I was unable to use the activityexecutioncontext inside of the virtual thread. After reading the error message I realized the reasoning wasn't sufficient, and decided to check if the code just hadn't implemented it.

2. How was this tested:
   There are unit tests, also created a local testing suite against a built image

Hello @TbirdDuncan, thanks for your contribution.

Note that I can't take a look at your PR until you've signed the CLA. See the link to sign the CLA in messages from CLAassistant above.

Also, I'm puzzled by your description. As far as I see, there's nothing in CurrentActivityExecutionContext that would not work in virtual threads.

Would you mind opening an issue ticket providing details on what issues you faced?

I can open an issue, also looks like some weird git stuff going on with my user. I'll try and resolve that, signing the agreement doesn't seem to resolve it.

I believe this happens when the email in your commit is not the one associated with your github account.

Well i'll be damned, I guess this is why its important to open an issue first. I can't replicate it with recent versions...
