Refactor opendeck/32

[zvecr]

Description

Main aim was to remove process_record_kb logic, but figured it was worth updating while changing files.

• Disabling rgb keycodes while having all effects enabled is somewhat pointless
• Aligned default enabled features to general recommended
• Removed suspend_power_down_user/suspend_wakeup_init_user duplicating core behaviour
• RGB Matrix defaults to on, so post_init is pointless
• Removed "size optimisations" as the firmware is comfortably undersized without
