Removed all uses and implementations of set_vector() function across ERC32, LEON2, and LEON3 BSPs. Replaced with rtems_interrupt_handler_install() and rtems_interrupt_entry_install(). - Added ERC32_Clear_and_unmask_interrupt() and LEON_Clear_and_unmask_interrupt() for unmasking logic previously in set_vector(). - Deleted set_vector() definitions and implementations in each BSP. - Updated related obj.yml files. - Replaced set_vector() with rtems_interrupt_catch() in shared/gnatcommon.c.
