  [test][AArch64] Adjust vector insertion lit tests

The test cases test_insert_v16i8_insert_2_undef_base and
test_insert_v16i8_insert_2_undef_base_different_valeus in
CodeGen/AArch64/arm64-vector-insertion.ll was leaving element 8
in the vector as "undef" without any real explanation. It kind of
looked like a typo as the input IR looked like this
   %v.8 = insertelement <16 x i8> %v.7, i8 %a, i32 8
   %v.10 = insertelement <16 x i8> %v.7, i8 %a, i32 10
leaving %v.8 as unused.

This patch is cleaning up the tests a bit by adding separate test
cases to validate what is happening when skipping insert at index 8,
while amending the original tests cases to use %v.8 instead of %v.7
when creating %v.10.
