feat: reclaim all resources from an aborted SP

Once any execution context of an SP is aborted, all the resources of
the SP are reclaimed by SPMC. This patch creates a placeholder
function to this effect which can be populated with necessary actions
such as disabling all interrupts belonging to the SP.
