This allows to split monitor & stack_trace related targets.
Also move stack traces related functionality into MonitorBase.

If the platform does not have `std::string_view` (i.e. `absl::string_view` is not an alias of `std::string_view`) the lookup will cause build failure.

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

New wrappers:
- `AllowEpollWait` (`epoll_wait`, `epoll_pwait`, `epoll_pwait2`)
- `AllowInotifyInit` (`inotify_init`, `inotify_init1`)
- `AllowSelect` (`select`, `pselect6`)
- `AllowDup` (`dup`, `dup2`, `dup3`)
- `AllowPipe` (`pipe`, `pipe2`)
- `AllowChmod` (`chmod`, `fchmod`, `fchmodat`)
- `AllowChown` (`chown`, `lchown`, `fchown`, `fchownat`)
- `AllowReadlink` (`readlink`, `readlinkat`)
- `AllowLink` (`link`, `linkat`)
- `AllowSymlink` (`symlink`, `symlinkat`)
- `AllowMkdir` (`mkdir`, `mkdirat`)
- `AllowUtime` (`utime`, `utimes`, `futimens`, `utimensat`)
- `AllowAlarm` (`alarm`, `setitimer`)
- `AllowGetPGIDs` (`getpgid`, `getpgrp`)
- `AllowPoll` (`poll`, `ppoll`)
Updated wrappers:
- `AllowOpen` now includes `creat`. `openat` already grants the ability to create files, and is the designated replacement for `creat` on newer platforms.
- `AllowStat` now includes `fstatfs` and `fstatfs64`. The comment already claimed that these syscalls were included; I believe they were omitted by accident.
- `AllowUnlink` now includes `rmdir`. `unlinkat` already grants the ability to remove empty directories, and is the designated replacement for `rmdir` on newer platforms.

On successful completion, `unw_step()` returns a positive value
if the updated cursor refers to a valid stack frame,
or `0` if the previous stack frame was the last frame in the
chain. On error, the negative value of one of the error-codes
below is returned.

This change adds support for using the `includes`, `include_prefix` and
`strip_include_prefix` attributes of the `cc_library()` rule. Without it,
the libtooling based header generator will not be able to find all
necessary includes as it is much stricter than the current libclang based
one in that regard.

Use locally unqualified types to filter ordered type declarations in
`TypeCollector::GetTypeDeclarations()`. This is necessary, as
`clang::TypeName::getFullyQualifiedName()` and
`TypeDecl::getQualifiedNameAsString()` have different ideas which
qualifiers belong to the name. The former works on `QualType`s, while
the latter deals with the declaration directly. This change decays a
`TypeDecl` into its locally unqualified `QualType`.
