Fix src/tests/build.sh argument processing

[sbomer]

In #81439 I added logic to src/tests/build.sh that would support the same syntax as the cmd script for the test filter args. However, this isn't working correctly because the shift happens inside a sourced script, and doesn't actually shift the outer arguments. The right way to do this is via __ShiftArgs.

Without this fix, tree nativeaot was working because nativeaot happened to be a supported argument as well. With the fix, other test subtrees work as expected.

Looks good to me, thanks Sven! Please note however that @jeffhandley is right now reviewing

#81733

including a broad revamp of the script so please consider syncing up with him to incorporate your change in his, otherwise you'll end up with a huge conflict and will need to basically redo your change.

Thanks for tagging me here, @trylek. I just merged #81733 and I think we'll be clear of merge conflicts.
