GHA: Test macos-14 - Githubissues

switch to macos-14 previous issues with macos-14 were a mix of #1388 and caching with seemingly random switching between macos-12 and macos-14 runners when using macos-latest
include arch in cache keys; use uniform cache keys
change some imports in test/sample/test_sample.py to be able to run subsets of tests despite missing optional dependencies
adjust resource limits to avoid random failures such as:
