More native support like RaspberryPi image

[srbala]

AlmaLinux RaspberryPi image should more native support which are available in standard RaspberryPi. Following are good to have in consideration to native support ...

• [ ] Configure WiFi on first time boot using config network-data file from boot partition
• [ ] Create new using user-data config file, create new user on first boot
• [ ] Configure user SSH settings based on ssh config entry
• [ ] Expand root partition (running rootfs-expand command
• [ ] Make config.txt file updated based on user prompt - screen rescan required etc
