fix : relocate QEMU example binaries to build directory

This change moves the QEMU example binaries from the source tree
to the build directory, following standard build practices.

Key changes:
- Created dedicated QEMU_ELF_PATH for output binaries
- Updated qemu-hello.mk to generate files in the build directory
- Fixed all qemu.bat scripts to use the new binary locations
