[CIR][AArch64] Add support for the remaining vceqz builtins (#185440)
Implement the remaining CIR lowerings for the AdvSIMD (Neon)
`vceqz` intrinsic group (bitwise equal to zero).

Most variants of `vceqz` variant were already supported; this patch
completes the rest of the group [1] that was left as a TODO.

Tests for these intrinsics are moved from:
  * test/CodeGen/AArch64/neon_intrinsics.c
  * test/CodeGen/AArch64/v8.2a-fp16-intrinsics.c

to:
  * test/CodeGen/AArch64/neon/intrinsics.c
  * test/CodeGen/AArch64/neon/fullfp16,

respectively.

The implementation largely mirrors the existing lowering in
CodeGen/TargetBuiltins/ARM.cpp.
