9299156727 CMake: Use toolchain info for system includes
CMake already provides `CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES`, so there's
no need to invoke the compiler to determine system include directories.

For the Clang tool based header generator, adding the includes from the
current toolchain is strictly more correct than having it try and figure them
out itself (which will favor files from any installed libc++ and/or Clang).

4ec1c6be64 CMake: Update policy settings to 3.26
This avoids a warning in newer CMake versions. For `CMP0083`, we still need to
explicitly select `NEW` behavior. `check_pie_supported()` will error if it is
unset even on later CMake versions.

5b12071ba0 Remove WaitForSanitizers from ptrace monitor & add to global forkserver
This makes should ensure global forkserver will be single threaded before forking the sandboxees as it does not go through WaitAndFork.

Waiting for sanitizers is not needed in the monitor and should reduce latency
by 1 second for all sanitizer builds. Currently it'll always wait up to 1 seconds for the process to become single-threaded, which will never happen as monitor itself is running in a separate thread.

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
