perfetto: switch to C++17 with temporary C++11 opt-out
* make all targets build with C++17
* make it an error to compile with C++11 without defining an opt-out
flag. The error makes it clear that any objections need to be
discussed very soon
* Keep the debug CI bot compiling with C++11 to prevent accidental
use of C++14/17 features in the transition period
