Add the common state needed by Octeon's selector-driven COP2 crypto
interfaces. This includes the selector constants and storage for the base
hash, AES, CRC, GFM, 3DES, KASUMI, and SNOW3G engines, plus the shared
selector-window mode used by overlapping hardware register banks.
Describe the shared HSH/SHA512, SHA3, SNOW3G, and ZUC selector window up
front so later engine patches only add their own selectors and state
instead of rewriting common comments.
Migrate the state in an Octeon-only subsection so non-Octeon CPU models do
not grow migration data. Later patches wire helpers and explicit selector
decode on top of this state.

Changes v7 -> v8:
- Split COP2 crypto state and migration coverage out of the combined
COP2 crypto core patch.

I guess you're using uint32_t instead of MIPSOcteonSharedMode for ease of
migration?
