Meta: Add install-native-partition CMake target installing to a real FS

Browse source 
While playing around with getting serenity to run on my main desktop
machine I wanted a way of easily updating my physical serenity
partition.

To use it you just need to:
- Create and format your local partition to ext4
- Set `SERENITY_TARGET_INSTALL_PARTITION` to the partition /dev path.
- Run the `install-native-partition` build target.

Example:

    $ export SERENITY_TARGET_INSTALL_PARTITION=/dev/nvme1n1p3
    $ cd serenity/Build/x86_64
    $ ninja install-native-partition
