[roll] Roll fuchsia [kernel][arm64] Sanitize EL2 registers before dropping to EL1

Ensure that MDCR_EL2, HSTR_EL2, CNTHP_CTL_EL2, and FGT registers
(if supported) are sanitized when dropping from EL2 to EL1.

For MDCR_EL2, we preserve PMCR_EL0.N in HPMN to allow EL1 access
to PMU counters, while zeroing other bits. Other registers are
zeroed to disable traps.
