Auto merge of #16924 - poliorcetics:ab/push-kxwqvtypvlsq, r=Veykril

feat: Add `rust-analyzer.cargo.allTargets` to configure passing `--all-targets` to cargo invocations

Closes #16859

## Unresolved question:

Should this be a setting for build scripts only ? All the other `--all-targets` I found where already covered by `checkOnSave.allTargets`
