PlacementWorld.cpp includes Poco JSON via JsonDocument.h, but the
building module did not declare THIRDPARTY poco, so those TUs compiled
without POCO_NO_AUTOMATIC_LIBS. MSVC then recorded a link of
PocoFoundationd.lib (the DLL debug name) instead of PocoFoundationmdd.lib.
Declare poco on building and apply the no-auto-link flags to every
native module, the host binary, and unit_test so a future JsonDocument
include cannot regress the Windows link.
