a627e7e9 - [clang][Sema] Deprecate `global`/`unknown` in `lifetime_capture_by` (#196635)

[clang][Sema] Deprecate `global`/`unknown` in `lifetime_capture_by` (#196635) Earlier, special `lifetime_capture_by` spellings `global` and `unknown` could conflict with actual parameter names, causing [some code](https://godbolt.org/z/YWhW1dnoe) to fail to compile. Because of that, we deprecate those parameters (they can probably be removed in the near future) #192102 Assisted-by: GPT-5.4 for cleanup
