cpp,qt: Remove C++ and Qt bindings

* README: Update.
* configure.ac: Remove checks, variables and file generations related to
the C++/Qt bindings. Remove cpp and qt* from available_languages and
default_languages.
* lang/Makefile.am (DIST_SUBDIRS): Remove cpp and qt.
* lang/cpp, lang/qt: Remove.
* m4/ax_check_compile_flag.m4, m4/ax_cxx_compile_stdcxx.m4,
m4/ax_gcc_func_attribute.m4, m4/pkg.m4, m4/qt5.m4, m4/qt6.m4: Remove.

The C++ and Qt bindings have been moved to separate Git repositories:
gpgmepp and gpgmeqt.

-/**
-   @short An abstract base class for asynchronous signing
-
-   To use a SignJob, first obtain an instance from the CryptoBackend
-   implementation, connect the progress() and result() signals to
-   suitable slots and then start the signing with a call to
-   start(). This call might fail, in which case the SignJob instance
-   will have scheduled it's own destruction with a call to
-   QObject::deleteLater().
-
-   Alternatively, the job can be started with startIt() after setting
-   an input file and an output file and, optionally, signers or flags.
-   If the job is started this way then the backend reads the input and
-   writes the output directly from/to the specified input file and output
-   file. In this case the signature value of the result signal will always
-   be empty. This direct IO mode is currently only supported for OpenPGP.
-   Note that startIt() does not schedule the job's destruction if starting
-   the job failed.
-
-   After result() is emitted, the SignJob will schedule it's own
-   destruction by calling QObject::deleteLater().
