boost: update to 1.71.0

Some notes:
- bjam bootstrap scripts were changed, and the patch for that had to be
  adjusted. tools/build/src/engine/build.sh now supports an --debug option
  which the bjam-native recipe can use to get the debug build of b2.
- a related patch was added to address a speed regression with the debug
  version of bjam
- gcc.jam patch had to be refreshed because boost added more "cpu-flags"
  lines.
- since 1.70.0, boost includes new cmake config files which are packaged
  in ${PN}-dev now so they make it into the SDK. (although 1.71.0 is needed
  to fix some bugs in them)
