changes to UBOOT_EXTLINUX_FDTOVERLAYS:x
do_create_extlinux_config is using a bit of an odd mechanism which
doesn't work well with sstate cache invalidation.
BitBake will detect changes to UBOOT_EXTLINUX_FDTOVERLAYS because it's
explicitly mentioned in the task, but it'll miss changes to
UBOOT_EXTLINUX_FDTOVERLAYS:label because this OVERRIDES is set within
the task, so the value of UBOOT_EXTLINUX_FDTOVERLAYS for the label
OVERRIDES will only ever change from within the task, while it is
running, much later than during parsing.
For that to work properly, we need to add the entire variable (including
the OVERRIDES part) to the vardeps varflag of the task so that its value
is monitored. This is already done for all possible label variables but
FDTOVERLAYS was forgotten.

Also known as FDTO, DTO or Device Tree Overlay.
This adds a new property per label in extlinux.conf for which device
tree overlays to apply on top of the base device tree (the one specified
in FDT or guessed by the bootloader if only FDTDIR is set). It is a
space-separated list of paths to the .dtbo file(s).
Note that the base FDT needs to have symbols enabled (DTC_FLAGS needs to
have -@ in it) for an overlay to be applicable.
This is only applicable for non-FIT setups.

The three blocks share the same LABEL and KERNEL content, so let's
factor that part out.

uboot-extlinux-config allows to specify multiple "labels" (entries in a
menu, à-la grub) and each of them have their own values for some fields.
Each "base" variable, e.g. UBOOT_EXTLINUX_FDT can be overridden for each
label. This is done via the OVERRIDES mechanism based on the label name,
e.g. UBOOT_EXTLINUX_FDT:linux if linux is a label.
However, OVERRIDES doesn't contain the label globally because it's only
necessary in one task. Therefore, the OVERRIDES itself is modified
within the task. This means that the sigdata will not be told the
dependency on UBOOT_EXTLINUX_FDT:linux, because it cannot know about it.
For this reason, we need to explicitly specify which variables this task
depends on via vardeps varflag for the task.
This was done in the past, but we missed updating it during the override
syntax migration so the cache wouldn't get invalidated if someone
modifies UBOOT_EXTLINUX_FDT:linux from a configuration file or a
bbappend for example.
Let's fix this by migrating it to the new syntax.

Add new UBOOT_EXTLINUX_MENU_TITLE variable that allows configuring
the "MENU TITLE" entry.
If set to empty, "MENU TITLE" will not be added to the output file.

The comment specifies how to use the variables but uses the older and
now unsupported override syntax. Let's update to match the newer syntax.

Move classes to classes-global or classes-recipe as appropriate to take
advantage of new bitbake functionality to check class scope/usage.
