boost: revert 1.72.0 regression

https://www.boost.org/users/history/version_1_72_0.html

 documents a
"Known Issue" and has a revert patch for an issue that causes code to
fail to compile that includes the coroutine function. Without this
patch, code which includes the asymmetric_coroutine.hpp will fail to
compile.
