* ghidra: 9.04 -> 9.1
Update Ghidra from 9.04 to 9.1
* ghidra: Added desktop file
Add a desktop file for Ghidra
Ghidra ships its icons as a .ico file, which isn't support by freedesktop. This means that to have icons, we need to extract the pngs from ghidra.ico, then copy them to the relevant folders.
This adds a requirement on a library to extract them, and also requires them to be copied over, which isn't ideal.
