Armv8.1-M: Add native x1 Keccak implementation

[mkannwischer]

Add a scalar x1 Keccak permutation to the Armv8.1-M FIPS202 backend, complementing the existing x4 MVE implementation.

The assembly is derived from XKCP, with ARMv7-M optimizations by Alexandre Adomnicai (ePrint 2023/773) and further optimizations in the SLOTHY M7 paper by Abdulrahman, Kannwischer, and Lim (ePrint 2025/366).

The implementation uses bit-interleaved state representation internally, with C wrapper functions handling the conversion to/from standard representation for now. Optimized xorbytes, and extractbytes (including the bitinterleaving) will be added at a later stage which will allow removing the current bitinterleaving.
