Building Boost-1.83.0 Libraries with latest clang compiler fails.

Note: Build of the Boost-1.83.0 Libraries succeeds with cxxstd=14 instead of cxxstd=17.

$ clang++ --version

PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.

Is this yet another duplicate of #39319 ?

Indeed, this assertion is also solved by https://reviews.llvm.org/D148474, same as #39319.

ResolveConstructorOverload needs to check properly if we are going to use copy
elision we can't use a conversion function.

This should fix 'Assertion failed: (isa<To>(Val) && "cast<Ty>() argument
of incompatible type!")' errors when building devel/boost-libs,
specifically libs/url/src/segments_view.cpp.

Bump __FreeBSD_version so this fix can easily be detected from
devel/boost-all/compiled.mk.
