part: efi: Disable overlap check
The current code checks that no partitions overlap with the GPT partition
table using the offset of the first LBA usable for that partition.
This works fine, unless you have a partition entry that is further away
than it usually is and you want to create partitions in the gap between the
GPT header and the GPT partition entries, for example to reflash a
bootloader that needs to be set there.
Rework the test to something a bit smarter that checks whether a partition
would overlap with either the GPT header or the partition entries, no
matter where it is on the disk.
Partitions that do not have a start LBA specified will still start at the
first LBA usable set in the GPT header, to avoid weird behaviours.

part: efi: rework the partition start and size in gpt_fill_pte
The start variable is only used inside a loop, and is never affected inside
it, so it's a purely local variable.
In the same way the partition size is accessed several times, so we can
store it in a variable.

GPT: add accessor function for disk GUID
In order to read the GPT, modify the partition name strings, and then
write out a new GPT, the disk GUID is needed. While there is an
existing accessor for the partition UUIDs, there is none yet for the
disk GUID.
Changes since v6: none.

partitions: increase MAX_SEARCH_PARTITIONS and move to part.h
Move MAX_SEARCH_PARTITIONS to part.h so that functions in cmd
directory can find it. At the same time, increase the value to
64 since some operating systems use many, and the resources
consumed by a larger value are minimal.
Changes since v6: none.
