Merge bitcoin/bitcoin#24132: build: Bump minimum Qt version to 5.11.3

956f7322f6 build: Bump minimum Qt version to 5.11.3 (Hennadii Stepanov)
e22d10b936 ci: Switch from bionic to buster (Hennadii Stepanov)

Pull request description:

  The current minimum Qt version is 5.9.5 which has been set in bitcoin/bitcoin#21286.

  Distro support:
  - centos 7 -- unsupported since bitcoin/bitcoin#23511
  - centos 8 -- [5.15.2](http://mirror.centos.org/centos/8/AppStream/x86_64/os/Packages/qt5-qtbase-5.15.2-3.el8.x86_64.rpm)
  - buster -- [5.11.3](https://packages.debian.org/buster/libqt5core5a)
  - bullseye  -- [5.15.2](https://packages.debian.org/bullseye/libqt5core5a)
  - _bionic_ -- [5.9.5](https://packages.ubuntu.com/bionic/libqt5core5a)
  - focal -- [5.12.8](https://packages.ubuntu.com/focal/libqt5core5a)

  As another Ubuntu LTS is coming soon, it seems unreasonable to stick to Qt 5.9 which support [ended](https://www.qt.io/blog/2017/06/07/renewed-qt-support-services) on 2020-05-31. Anyway, it's still possible to build Bitcoin Core GUI with depends on bionic system.

  Bumping the minimum Qt version allows to make code safer and more reliable, e.g.:
  - functor-parameter overload of [`QMetaObject::invokeMethod`](https://doc.qt.io/qt-5/qmetaobject.html#invokeMethod-4)
  - fixed https://bugreports.qt.io/browse/QTBUG-10907

  An example of the patch using the functor-overload of `QMetaObject::invokeMethod`:
  ```diff

  -    bool invoked = QMetaObject::invokeMethod(walletModel, "unload");
  +    bool invoked = QMetaObject::invokeMethod(walletModel, &WalletModel::unload);
       assert(invoked);
   }

  ```
  It uses the same new syntax as signal-slot connection with compile-time check. Also see bitcoin/bitcoin#16348.

  This PR is intended to be merged early [after](https://github.com/bitcoin/bitcoin/issues/22969) branching `23.x` off.
