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.
