Fix windows CI (1.2.x) by adding ncurses (also a couple backports)

Fix windows CI build

The mingw-w64-python 3.9.12-2 update rebuilds python with a shared ncurses library instead of a statically linked one (which was required before mingw-w64-ncurses 6.3-5).

I didn't backport all the MRs with backportproposed on them, just the extremely safe ones.

All only affect dev versions so no need to document in release notes.
