bpf: add new negative selftests to cover missing check_func_arg_reg_off() and reg->type check
Add new negative selftests which are intended to cover the
out-of-bounds memory access that could be performed on a
CONST_PTR_TO_DYNPTR within functions taking a ARG_PTR_TO_DYNPTR |
MEM_RDONLY as an argument, and acceptance of invalid register types
i.e. PTR_TO_BTF_ID within functions taking a ARG_PTR_TO_DYNPTR |
MEM_RDONLY.
