Replace CONFIG_SYSTEM_TIME64 conditional atomic64 operations with a unified seqlock-based approach for managing the system tick counter. This simplifies code by eliminating architecture-specific branches and provides more robust thread-safe access patterns. Signed-off-by: hujun5 <hujun5@xiaomi.com>

Refactor the system tick counter synchronization mechanism in the scheduler
clock implementation to replace conditional atomic operations with a seqlock-based
approach. The existing implementation uses different code paths for 64-bit and
32-bit systems with explicit atomic operations, introducing complexity and
architecture-specific branching.
