arm64: add missing REG_SCTLR_EL1 initialization in signal processing

Browse Source 
Add REG_SCTLR_EL1 system register initialization in arm64_init_signal_process
when setting up register context for signal handlers. Initialize with current
sctlr_el1 value and apply CONFIG_ARM64_MTE settings if enabled. Fixes regression
where signal handler context was missing critical system control register setup.
