Two Installation Modes: Clean Install and Dual-Boot

[chris-romanov]

Hi @mszoek,

Description: This pull request introduces two installation modes for the ravynOS installer:

1. Clean Install: • This option wipes the entire disk and performs a fresh installation of ravynOS. • Thoroughly tested multiple times, and everything works as expected.
2. Dual-Boot Installation: • This option allows ravynOS to coexist with an existing operating system by utilizing the existing EFI partition. • This feature has not been fully tested yet and requires further refinement.

I would greatly appreciate feedback, suggestions, and testing, especially for the Dual-Boot mode. Let me know your thoughts! 😊

If ravynOS is already installed on the disk, the installation script blocks the Dual Boot option. Only the Clean Install option will be available.

Fixed several issues. Changed folder names from efi to EFI, EFI\RAVYNOS, EFI\BOOT. UEFI SPECS
