bpf: Add __bpf_dynptr_data* for in kernel use
Different types of bpf dynptr have different internal data storage.
Specifically, SKB and XDP type of dynptr may have non-continuous data.
Therefore, it is not always safe to directly access dynptr->data.
Add __bpf_dynptr_data and __bpf_dynptr_data_rw to replace direct access to
dynptr->data.
Update bpf_verify_pkcs7_signature to use __bpf_dynptr_data instead of
dynptr->data.
