feat(sme): add sme helper routines and add streaming sve support

This patch adds a few helper routines to set the Streaming SVE vector
length (SVL) in the SMCR_EL2 register, to enable/disable FEAT_SME_FA64
and to get CPU's Streaming SVE mode status.

This patch also makes SVE compare routines compatible for both normal
SVE and streaming SVE mode.
