b258535161 Treat libunwind sandbox as a ~regular sandboxee
This removes dependency on unwind from forkserver,
which should reduce binary size for all the custom forkservers (also the SAPI generated ones).
Unwind was only ever used by the global forkserver anyhow

0d3d5d4bcb Seccomp_unotify based monitor
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

2f64d3d925 stack_trace: pass fd to sandboxee's memory instead of using process_vm_readv
Libunwind sandbox no longer needs to join sandboxee's userns.
This cleans up a lot of special handling for the libunwind sandbox.

e88755256d Use FDCloser in Executor extensively
Also really own `exec_fd_` as previously if the executor is destructed without calling `StartSubProcess` the file descriptor would leak.

dbaf95c724 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.

4e20e0702a Use full workspace name to access Bazel packages in generator
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.
