Fix compilation with upcoming Boost 1.87.0

[cho-m]

Issue

Fixes #7072. Locally compiles for me in Homebrew environment patching on top of master or v5.27.0.

Since code base already uses boost::asio::io_context, that guarantees a minimum of Boost 1.66.0, so there shouldn't be compatibility issues.

Change based on boostorg/asio@b60e92b, e.g., example/cpp03/http/server/server.cpp has:
