Avoid using pointers to temporary copies of desired extensions.

validExtensions now references data that remains constant for its entire life-time.

Thank you @ItsBasi for the contribution, looks good. Were you able to test it locally? Currently the unit tests that run with extensions are not part of the Ci due to CPU runner limitations, so you'd need to run the tests locally to validate

All 51 test's passed. Although i did not see that any of the run test actually used extensions, so the issue never does surface.

@ItsBasi you are totally right, it seems I was confusing this example which is not currently in the tests https://kompute.cc/overview/advanced-examples.html#add-extensions

Ok given that all tests pass we can merge, and we can look at adding a test that validates a correct and incorrect extensions (which can work on the CI) - is taht something that you could also be interested in exploring to add?
