Adding Edl button in reboot menu

Edl mode is available only on qualcomm devices and it used to fully
restore the bricked devices. I made the button available only if
TW_HAS_EDL_MODE := true like the download button. I set the edl
button to the right of the download button, so devices can support
edl button and download button. I also added the translation for
all languages.
