Sema: Fix many-pointer array concatenation at comptime  (#11512)

* Sema: Correctly determine whether array_cat lhs and rhs are single ptrs

Many-pointers are also not single-pointers and wouldn't be considered
here. This commit makes the conditions use the appropriately-named
isSinglePointer instead.

* Sema: Correctly obtain ArrayInfo for many-pointer concatenation

Many-pointers at comptime have a known size like slices and can be used
in array concatenation. This fixes a stage1 regression.

* test: Add comptime manyptr concatenation test
