bpf: Add AND verifier test case where 32bit and 64bit bounds differ



If we AND two values together that are known in the 32bit subregs, but not
known in the 64bit registers we rely on the tnum value to report the 32bit
subreg is known. And do not use mark_reg_known() directly from
scalar32_min_max_and()

Add an AND test to cover the case with known 32bit subreg, but unknown
64bit reg.
