dm vdo: add geometry block initialization to encodings.c

Add vdo_initialize_volume_geometry() to populate the geometry block,
computing the space required for the two main regions on disk.

Add uds_compute_index_size() to calculate the space required for the
UDS indexer from the UDS configuration.

dm vdo: remove redundant TYPE argument from vdo_allocate macro

We can infer the type needed from the supplied pointer argument. A
couple invocation sites needed fixing to supply the proper type of
pointer.

Use overflow.h's size_mul, and we can remove the __vdo_do_allocation
wrapper which did the same overflow check.

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.
