5.2 library updates, part 1
This MR proposes some painless (mostly) updates to 3rdparty.
Only noteworthy one in this MR is Boost, which goes to 1.80 across all versions, and triggers a bug in Python 3.8 header: it mistakenly redefines vsnprintf, which is already available in MSVC and MinGW. The bug is easily worked around by blocking the redefinition.
Test Plan
I need @ivany and @szaman to give it a look, I confirmed Windows builds work.
