revive old V3 buildenv for esp32 (optional)

Allow users to build with the old "V3" framework if they want. All release builds are still using V4. * fixed wrong references in some legacy envs * added ${esp32_legacy.build_unflags} * changed esp32_4MB_S_base and esp32_4MB_M_base to use old V3 framework
