test(*): Migrate away from deprecated addSpanProcessor in tests

[chancancode]

This migrates from the deprecated addSpanProcessor method to the constructor option in preparation for the upcoming SDK 2.0 release.

This commit migrates all usages in tests for each package, and there are no changes to the runtime code. It's a lot of changes, but since it's all in tests, as long as the tests pass, I don't think there is anything risky in here. It probably doesn't need a CHANGELOG entry either.

Ref #2645 (cc @pichlermarc)
