Linux 7.3 streamlines code by removing the CONFIG_COMPAT_32BIT_TIME Kconfig option for disabling 32-bit time system calls

WHY IT MATTERS

This change simplifies kernel maintenance by eliminating a rarely used configuration option. It enforces Year 2038-safe time handling but may break compatibility with older 32-bit applications relying on legacy time system calls.
