Adds a command called "gpt transpose" which will swap the order two
partition table entries in the GPT partition table (but leaves them
pointing to the same locations on disk).
This can be useful for swapping bootloaders in systems that use an A/B
partitioning scheme where the bootrom is hard coded to look for the
bootloader in a specific index in the GPT partition table.

The EFI doesn't allow removal of handles, unless all hosted protocols
are cleanly removed. Our efi_delete_handle() is a bit intrusive.
Although it does try to delete protocols before removing a handle,
it doesn't care if that fails. Instead it only returns an error if the
handle is invalid. On top of that none of the callers of that function
check the return code.
So let's rewrite this in a way that fits the EFI spec better. Instead
of forcing the handle removal, gracefully uninstall all the handle
protocols. According to the EFI spec when the last protocol is removed
the handle will be deleted. Also switch all the callers and check the
return code. Some callers can't do anything useful apart from reporting
an error. The disk related functions on the other hand, can prevent a
medium that is being used by EFI from removal.
The only function that doesn't check the result is efi_delete_image().
But that function needs a bigger rework anyway, so we can clean it up in
the future

It is is sometimes desired to be able to skip decrementing the number of
tries remaining in an Android A/B boot, and instead just check which
slot will be tried later. This can commonly be be the case for platforms
that want to A/B u-boot itself, but are required to boot from a FAT MBR
partition. In these cases, u-boot must do an early check that the MBR
points to the correct A/B boot partition, and if not rewrite the MBR to
point to the correct one and reboot. Decrementing the try count in this
case is not desired because it means that each u-boot might constantly
ping-pong overwriting the MBR and rebooting until all the retries are
used up.
