Merge #18738: build: Suppress -Wdeprecated-copy warnings
0c63f808542ba02fc41aa90b1d96e9123f16d8ad build: Suppress -Wdeprecated-copy warnings (Hennadii Stepanov)
Pull request description:
Tomorrow, on Apr 23 the Ubuntu 20.04 release is expected. It packaged with Qt 5.12 LTS that has a nasty peculiarity to cause modern compilers, including Clang 10.0 and GCC 9.3, to emit spammy `-Wdeprecated-copy` warnings (#15822, #18419).
This PR suppress such warnings _temporarily_, until the [upstream is fixed](https://codereview.qt-project.org/c/qt/qtbase/+/272258).
Here are some affected systems (with system packages):
- Ubuntu 20.04 LTS + Qt 5.12.8 LTS + { Clang 10.0 | GCC 9.3 }
- Fedora 32 + Qt 5.13.2 + Clang 10.0

MarcoFalke:
ACK 0c63f808542ba02fc41aa90b1d96e9123f16d8ad seems fine to disable this warning for the 0.21.0 release temporarily and then enable it for 0.22.0, when boost is removed.
fanquake:
ACK 0c63f808542ba02fc41aa90b1d96e9123f16d8ad - I think it's ok to suppress these for now, given that `-Wdeprecated-copy` is enabled (via `-Wextra`) in GCC 9 and Clang 10. The Qt output is pretty noisy, and there's a few warnings from Boost as well.
