esp32: Rename esp32.common.ld to esp32.project.ld to avoid build errors when downgrading Linker script generator produces build/esp32/esp32.common.ld from components/esp32/ld/esp32.common.ld.in This works fine until IDF is downgraded to V3.1 which uses components/esp32/ld/esp32.common.ld and doesn't track build/esp32/esp32.common.ld at all. At this point, the linker runs in the build/esp32 directory and "-T esp32.common.ld" picks up the linker script generated .ld file, which causes mis-builds.
