Boost: Improve search algorithm
The new implementation will correctly pick boost from 3 possible
locations on windows and two locations on posix compatible OSs.
The new search algorithm also differentiates between debug and
release builds of Boost and multi or single threading builds.
It was also decided to map "Meson modules" to Boost software libraries
and not Boost modules since it there are a lot of options regarding
linking. Some modules can even be used either as headers-only or with
dynamic linking.
This commit also fixes a bug that prevented header-only use on Windows.
Fixes: #2274 #2239 #1803 #669
