wolfssl: Use Absorb/SqueezeBlocks API for SHAKE-128/256 XOFs

This API is available since 5.5.1 (released in 2022) and allows us to
avoid the inefficient previous implementation (don't think it's worth
keeping that around for older versions).  Also added support for
SHAKE-128.  Note that the only user of SHAKE is the ml plugin nowadays
and since wolfSSL also provides ML-KEM, this might not actually
get used much.
