   #32269 rebased.

   I had trouble building bitcoin core the way I wanted since now more features require a flag while building. IMO it makes sense to make it a bit more prominent in the build docs how to get the needed flags.

   For all other platforms, this configure help lives close to the cmake --build build command, which makes most sense to me. I did note that build-windows.md and build-windows-msvc.md documentation does not provide the cmake -B build -LH help at all. If relevant, could be added in this PR? No blocker.

   This PR moves information on getting all the available options of cmake -B build to a more prominent place, line 13. The PR seems to me a logical change and makes me wonder why this information was at the end of the documentation in the first place.

    (might make sense to mention ccmake too?)
