headline: Libgomp: Fix missing disassociation in target pointer management.
tldr: Addresses a multi-device issue by ensuring that target pointers are disassociated after being associated in OpenMP target regions.
why_it_matters: In multi-device OpenMP environments, failure to disassociate pointers can lead to execution errors. This fix ensures correct pointer management.

The commit addresses an issue where ‘omp_target_disassociate_ptr’ was not called after ‘omp_target_associate_ptr’ in the ‘libgomp.c/omp_target_is_present.c’ test case. This oversight could lead to test failures, especially in multi-device settings. The fix adds the missing disassociation step.
