Use the Extended Bootloader Partition GUID for `/boot`, instead of the
Linux filesystem data GUID. This is useful for autodetection of a
partition purpose based on its GUID without reading the `/etc/fstab`
first.
Ensure that when creating mountpoints, e.g. when converting the
partitions layout to LVM, the `/boot` partition get the proper GUID
assigned.
Regenerate RHEL-90 and centos-9 image test cases.

Since udev will probe block devices it is advisable to hold a lock
on the device when modifying its partition table or the superblock
of the filesystem (see [1]). osbuild loopback devices do support
this via the `lock` option. Set this option for all operation that
involve changing block device "metadata" that could potentionally
race with udev, such as sfdisk, mkfs, creating a luks2 container
and creating LVM2 volume groups and logical volumes.
NB: osbuild also has its own device inhibition logic to prevent
udev/lvm2 from auto activating devices and in general to limit the
interaction between the host and devices used by osbuild. See [2]
for more information.
NB: this also locks the loopback device in situation where we the
it is strickly not the right thing to do, e.g. when creating a fs
on a logical voume that is located on a loopback device, since in
this case the device we would need to lock is the logical volume.
Sadly, LVM/DM devices are exempt from block device locking. But,
due to a bug in osbuild < 50, the udev inhibitor does *not* work
for loopback devices and therefore we have to use the actual lock
to preven LVM device auto-activation via `69-dm-lvm-metad.rules`.
The change was implemented by adding a new boolean to `getDevices`
indicating if the loopback device should be locked or not. Once
we depend on osbuild 50 we can change the logic in `getDevices`
to only lock the loopback device if the number of devices is one,
i.e. we are working directly on the loopback device.

Whenever we create a new mountpoint due to a user customization,
ensure the layout uses LVM, i.e. convert plain layouts to it, if
needed. This does not apply to rpm-ostree based systems, e.g. the
simplified installer since they will be using LUKS in 9.0.
Add "lvm2" to the build pipeline and thus generate new manifests
and image infos.

With the new grub2 stage options we have the following changes to the
grub2 stage:
- Set the WriteCmdLine flag to false to not write kernel command line
options to grubenv.
- Don't set the kernel command line options in the stage options.
The kernel command line options are now only specified in the Kernel
command line stage (org.osbuild.kernel-cmdline) so we add all options
there:
- Image type options
- Blueprint options
- Partition-table-specific options
Updated manifests and image info.

Use entity based method `ForEachMountable` and `getDevices` to generate
all mounts and devices in a generic way, which then allows for mounts on
arbitrarily nested devices.
Update manifests and image info:
- New device names generated by `pathdot()` to avoid basename
collisions.
- Some partitions are generated in a different order now which changes
the order they appear in the manifest and their UUIDs.

Instead of hard coding a padding of 100 sectors for all layouts, i.e.
MBR and GTP, adjust the needed space depending on the layout: for MBR
we don't need to reserve any space at all since it does not have a
secondary header. For GTP we reserve 33 sectors, as indicated in the
UEFI specific, which allows for the header itself and up to 128 entries.
To not modify the layout of already released distributions, like RHEL
8.4 and 8.5, a new member called `ExtraPadding` is added to `Partition
Table` and then used in the corresponding layouts to preserve the
existing padding of 100.
