Unotify based monitor should bring big performance wins
if the sandboxee heavily uses threading or signals.
Some of the features are not supported in that mode:
- execveat is always allowed instead of just the initial one
- stack traces are not collected on normal exit or if the process is terminated by signal

Libunwind sandbox no longer needs to join sandboxee's userns.
This cleans up a lot of special handling for the libunwind sandbox.

Follow-up changes might be required to fully fix up the contrib sandboxes.

The feature is pure optimization, but it requires
additional syscalls.

Also really own `exec_fd_` as previously if the executor is destructed without calling `StartSubProcess` the file descriptor would leak.

- Assign to `*mutable_XXX()` instead of looping
- Use a const ref for capabilities

Also accept `absl::string_view` and `absl::Span<const std::string>` arguments.
Drive-by:
- Move using declaration into namespace

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.

Since the interface generator is invoked via a Bazel macro, it will be
expanded in the embedding context of the project using SAPI, so package access
needs to go through the full workspace root @com_google_sandboxed_api.
This change also modifies the CMakeLists.txt accordingly, as the "external"
subdirectory is no longer needed/wanted.
