  [clang][CIR][AArch64] Add lowering for conversion intrinsics (#209252)

This PR adds lowering for intrinsic from the following groups:
* https://arm-software.github.io/acle/neon_intrinsics/advsimd.html#conversions

It continues the work started in #190961, #193273 and #199990. This PR
implements the remaining conversions truncating to zero:
  * vcvtd_s32_f64
  * vcvtd_s64_f64
  * vcvtd_u32_f64
  * vcvtd_u64_f64

The corresponding tests are moved from:
  * clang/test/CodeGen/AArch64/

to:
  * clang/test/CodeGen/AArch64/neon/

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