Fix rare failure while starting the global forkserver
...
This bug only manifests if a lot of fds are open when global forkserver is started.
If the allocated exec_fd number was equal Comms::kSandbox2ClientCommsFD then it would be replaced by the comms fd and result in EACCESS at execveat.

Move utility code into sandboxed_api/util
...
This change should make it less confusing where utility code comes from.
Having it in two places made sense when we were debating whether to publish
Sandbox2 separately, but not any longer.
Follow-up changes will move `sandbox2/util.h` and rename the remaining
`sandbox2/util` folder.

Reimplement raw logging to avoid Abseil internals

The defined raw logging macros should be compatible with Abseil and
we can remove our version once Abseil releases theirs.
