Timothee Cour 1f1d85bb9c reuse config/build_config.txt for all bootstrap scripts (posix + windows + ci); use build_all.bat in 1 CI, fix bug in build_all.bat (#17899)
* reuse config/build_config.txt for all bootstrap scripts (posix + windows + ci)
* ci_docs: use build_all.bat in CI (just in that pipeline) to ensure it keeps working
* fixup
* fix pre-existing bug in build_all.bat
* fixup
* cp => copy /y
* auto-generate build_all.bat, build_all.sh
* fixup
