arm64/sme: Implement context switching for ZT0
When the system supports SME2 the ZT0 register must be context switched as
part of the floating point state. This register is stored immediately
after ZA in memory and is only accessible when PSTATE.ZA is set so we
handle it in the same functions we use to save and restore ZA.
