Apple clang v 15.0.0 cannot build registry

[andrew-platt]

Bug description
On a Mac using the default c compiler clang from Apple, the following error occurs while building the registry (dev branch at commit a98f8bc):

Compiler specifics:

Apple clang version 15.0.0 (clang-1500.3.9.4)
Target: x86_64-apple-darwin23.4.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

The alternative is to use the gcc compiler. However, we are likely to get questions on this if we don't address it.

The openfast_registry CMakeLists.txt file has the wrong version for the C++ standard. std::quoted is part of the C++14 standard, whereas the current version is listed as C++11. Most compilers in use should support C++14 so I'll summit a PR to change the required C++ standard version.

Fixed with #2210
