What this function is actually doing is to create a filesystem,
together with a new partition; for LVM that filesystem could
also be created on a new logical volume though.
The previous commit made sure that `PartitionTable.RootPartition`
is indeed returning the pointer partition object inside the array
of the `PartitionTable`. Thus changes to the returned object will
now directly affect the object and thus there is no need to call
`PartitionTable.updateRootPartition` anymore.
When we iterate over the partitions to find the root partition,
we are getting the partition by value so even if we return a
pointer to that then, it is actually a pointer duplicated object.
Return the pointer to the actual partition object instead.
In various places we are interested in the root and boot file-
systems. Currently those were accessed via by retrieving the
partition that contain them and the accessing the filesystem
member. Add accessors to `PartitionTable` that directly return
the needed filesystem. This will help if the file system is
stored inside a container like LVM or LUKS instead of directly
on a partition.
thozza pointed out that `int` is platform dependent which results in
a fs size that is too small for 32-bit machines. This commit changes
the filesystem custimizations to use `uint64` instead of `int`
Specifying the boot partition filesystem UUID in grub2 stage is required
in case the `/boot` mountpoint is on a separate partition. This is the
case of RHEL-8.5 and RHEL-9.0 `ami` and `ec2` images.
Extend `disk.PartitionTable` with a new `BootPartition` method, which
returns a pointer to partition with FS mountpoint `/boot` if there is
such partition, or `nil` otherwise.
Extend the RHEL-8.5 and RHEL-9.0 code creating options structure for
grub2 osbuild stage to include the boot partition in case it has been
provided.

Moved the function that searches for the boot partition index to the
PartitionTable struct as a method. The method returns -1 if not found
and it's now the responsibility of the caller to handle the case where
it is not found.
Now that we have an abstract partition table definition, we can use it to
generate org.osbuild.fstab stage options.
This is extremely nice because it removes magic contains.

Using osbuild.QEMUAssemblerOptions to encode a partition table was weird.
This commit introduces a disk package that contains data types for defining
partition tables. Also, there's a handy function to convert the abstact
partition table to osbuild.QEMUAssemblerOptions.
