Add support for JDK_VENDOR in playlists

[smlambert]

There may be several use cases where we want to differentiate by JDK_VENDOR (which is over and beyond differentiating by JDK_IMPL).

We have currently blended the meaning of JDK_IMPL with vendor (hotspot, sap, corretto, dragonwell are all hotspot VM impl based, but rightly we should categorize them as JDK_VENDOR (adopt, sap, amazon, alibaba) or whatever value is returned by a query of java.vendor. (related: adoptium/temurin-build#465)

As there are tests that may be vendor specific (many build/packaging tests for example).

Looking into this, so we can create the adopt-only test needed for adoptium/temurin-build#2226

This may end up to be a documentation effort, as JDK_IMPL is currently nearly equivalent to JDK_VENDOR and we may not have a need for an explicit VM_IMPL differentiator.

Will discuss with @renfeiw and @llxia this week.

Some discussion on the topic:
We currently populate JDK_IMPL with value returned from java.vm.name. We will look at what is returned by a query to java.vm.vendor (from each of the known/accessible OpenJDK distributors) and possibly use a combination of java.vm.name and java.vm.vendor.

I am working on a PR to add JDK_VENDOR. This information is really helpful!

@renfeiw - take a look at smlambert:vendor branch, where I started... but still didn't add the playlist element and ability to add filtering.

Fixed by #142 - thanks @renfeiw !
