fix: copy hiperiso EFI binaries to data partition during install

The chain boot path looks for hiperiso_x64.efi in /hiperiso/ on the data
partition. Without this, booting ISOs (non-memdisk) fails with
'ventoy not ready chain empty failed'.

The installer now mounts the data partition after writing the ESP image
and copies ./hiperiso/* (hiperiso_x64.efi, iso9660_x64.efi, udf_x64.efi,
vtoyutil_x64.efi, wimboot, memdisk, etc.) to it. This makes the ISO
chain boot work for non-memdisk boot modes.
