bpf, tests: Add BPF_MOV tests for zero and sign extension
Tests for ALU32 and ALU64 MOV with different sizes of the immediate value. Depending on the immediate field width of the native CPU instructions, a JIT may generate code differently depending on the immediate value. Test that zero or sign extension is performed as expected. Mainly for JIT testing.
