roll: pigweed pw_allocator: Add BlockResult

This CL improves on the previously introduced BlockAllocType to
communicate both the result of allocator requests as well as
side-effects to neighboring blocks.

Instead of being a simple enum and returning a `Result<BlockAllocType>`
from methods like `AllocFirst` and `AllocLast`, `BlockResult` uses
`StatusWithSize` to fit in a single word, and encodes separate values to
for both the previous and next blocks to inidcate how they have changed.

Additionally, `Resize` has been updated to return a `BlockResult`.
