dm vdo: save the formatted metadata to disk
Add vdo_save_super_block() and vdo_save_geometry_block() to perform
asynchronous writes of the super block and geometry block respectively.
Add vdo_clear_layout() to zero the UDS index's first block, the block
map partition, and the recovery journal partition.
These operations are driven by new phases in the pre-load state machine
(PRE_LOAD_PHASE_FORMAT_*), ensuring that disk writes happen during
pre-resume rather than during dmsetup create.

dm vdo: add formatting logic and initialization
Add the core formatting logic. The initialization path is updated to
read the geometry block (block 0 on the storage device). If the block
is entirely zeroed, the device is treated as unformatted and
vdo_format() is called. Otherwise, the existing geometry is parsed
and the VDO is loaded as before.
The vdo_format() function initializes the volume geometry and super
block, and marks the VDO as needing it's layout saved to disk.

dm vdo: add geometry block structure
Introduce a vdo_geometry_block structure, containing a vio and buffer,
mirroring the existing vdo_super_block structure. Both are now
initialized at VDO startup and freed at shutdown, establishing the
infrastructure needed to read and write the geometry block using the
same mechanisms as the super block.
Refactor read_geometry_block() to use the new structure.

dm vdo: add formatting parameters to table line
Extend the dm table line with three new optional parameters:
indexMemory (UDS index memory size), indexSparse (dense vs sparse
index), and slabSize (blocks per allocation slab). These values are
parsed, validated, and stored in the device configuration for use
during formatting.
Rework the slab size constants from the single MAX_VDO_SLAB_BITS into
explicit MIN_VDO_SLAB_BLOCKS, MAX_VDO_SLAB_BLOCKS, and
DEFAULT_VDO_SLAB_BLOCKS values.
Bump the target version from 9.1.0 to 9.2.0 to reflect this table
line change.

dm vdo: update vdo_allocate_extended to take a field name, no types
All of VDO's "extended" allocations use a flexible array field at the
end of the allocated structure. We can infer the struct type from the
supplied pointer. Replacing the array field type with the field name
lets us use struct_size from overflow.h to compute the size instead of
the local __vdo_do_allocation version.
One allocation of bio structures doesn't conform to this pattern,
since the removal of bi_inline_vecs; directly compute the total size
for that case.
