Description
Implement changes to SIMD SHA-256 and to some formats that use it, similarly to what #5425 did for SHA-512.

Research direction
Start by comparing this issue with #5425, then locate the SIMD SHA-256 implementation and the formats that use iterated hashing. Determine which half-length input paths and tests are affected; done means the specialized behavior matches the SHA-512 precedent without breaking those formats.
