[PATCH v3] tests/intel/xe_exec_capture: Enhance test to check with DUMPABLE flag

[pravalika gurram]

check if the VM is there when DRM_XE_VM_BIND_FLAG_DUMPABLE is set
in the generated devcoredump. check VM address within the range.
VM address is located after END_TAG and is at the end of dump, that's
why "stop on END_TAG" is removed.
