Currently, some of our code paths that run test targets don't correctly set the `DYLD_FRAMEWORK_PATH` and `DYLD_LIBRARY_PATH` arguments on macOS. This hasn't been a problem in practice because the XCTest helper tool is able to sort it out for us, but my plan with swift-testing is to run an executable directly (like we do for corelibs-xctest.) That means we'll have a code path that could potentially rely on XCTest or other Apple SDK bits, but which is not calling through the XCTest helper tool. This change hoists our setting of those arguments to a position where they are always set (on macOS only!) before we run a test target, regardless of build style. This change was previously landed as #7040 but was reverted (#7054) while we investigated a toolchain regression. We do not believe #7040 is the root cause of that issue, so this PR reapplies it.

This is very speculative revert at this point since I am unable to reproduce, but since last Wednesday, we have been seeing this issue on the nightly toolchain CI:
and this change seems to fit in timeline wise and also as it affects testing, so it becomes the most relevant candidate for a speculative revert. The process invocation code hasn't changed in a meaningful way in a long time, so it seems unlikely that the logic there is the culprit.
