vb2_shared_data struct has many offsets to other objects in the
workbuf. They are all prefixed with `workbuf_`, e.g.:
uint32_t workbuf_data_key_offset;
uint32_t workbuf_data_key_size;
In order to adhere to a hierarchical structure on the workbuf,
remove the workbuf_ prefix from these symbols to reflect the
relationship between vb2_shared_data and its children more
accurately.
Create a helper function vb2_member_of to safely look up a child
of a particular object in the workbuf by offset. Pointer
arithmetic to find vb2_shared_data children is replaced with
calls to this function.

To make explicit when vboot2 error codes should be returned,
use the new vb2_error_t type on all functions which return
VB2_ERROR_* constants.

Previously, workbuf used was not rounded up to a multiple of
VB2_WORKBUF_ALIGN. The next allocation would be aligned, but not
until it was made.
Change this to round up used size when more workbuf is used. This
provides better predictability of where the next allocation will be
placed.
Uncovered this problem when I added a new member to vb2_shared_data
which changed its size so it wasn't a multiple of VB2_WORKBUF_ALIGN,
and the vb20 and vb21 unit tests which tried to simulate not enough
buffer broke in strange ways.

Previously, vb2_unpack_key() actually unpacked a key buffer. Callers
that had a vb2_packed_key had to typecast it back to a uint8_t buffer to
unpack it. Rename vb2_unpack_key() to vb2_unpack_key_buffer(), and make
vb2_unpack_key() unpack a vb2_packed_key.

This allows the caller to load the kernel partition and then pass it
to vboot for verification, rather than having vboot assume the kernel
partitions are all on a block storage device.
Next up, APIs for the caller to parse partition information from a GPT
(yes, that's cgptlib, but we'll make it more easily callable by
depthcharge).
