[PATCH 00/14] test: Convert tests to use FsHelper and DiskHelper

[Simon Glass]

This series adds a DiskHelper class and converts most test code to use
FsHelper and DiskHelper instead of calling mk_fs() and setup_image()
directly.

The FsHelper class (already upstream) provides a cleaner interface for
creating filesystem images, handling temporary directories and cleanup
automatically. The new DiskHelper class builds on this, creating
partitioned disk images from one or more FsHelper filesystems.

DiskHelper includes a cur_dir flag to place the disk image in the
current directory rather than the persistent-data directory. This
matches the behaviour of setup_image() which places disk images in
source_dir where sandbox expects to find them. This flag is needed for
now and should be removed in a follow-up once all tests are migrated to
use the persistent-data directory instead.

With these helpers, test-setup code becomes shorter, more consistent and
easier to follow. Manual sfdisk/dd/cleanup sequences are replaced by a
few method calls.

The series also fixes a broken fs_obj_fat fixture where a stale
size_gran argument is silently causing the test to be skipped.

A few EFI test fixtures (efi_capsule, efi_secboot, eficonfig) still use
mk_fs() directly; these are left for a follow-up series since they would
benefit from a full DiskHelper conversion.
