FindBoost: Add support for Boost 1.79
Update the list of known versions.
Run the command
cmake -DBOOST_DIR=/path/to/boost_1_79_0 -P Utilities/Scripts/BoostScanDeps.cmake
to extract dependencies from the 1.79.0 source tree. They are the same as 1.78's dependencies, so just update the version check for warning about newer versions.
Fixes: #23452 (closed)
Backport: release
