sched/irq: align irq work queue stack buffer

Browse source 
Add aligned_data(STACK_ALIGNMENT) attribute to g_irq_work_stack buffer declaration
in irq_attach_wqueue.c. Ensures stack memory is properly aligned to architecture
requirements, preventing unaligned stack addresses that could cause data access
faults or performance degradation on strict alignment architectures.
