4a93b9a1 - [ARM] Lower strictfp vector fp16 rounding operations similar to default mode (#183700)

[ARM] Lower strictfp vector fp16 rounding operations similar to default mode (#183700) Previously the strictfp rounding nodes were lowered using unrolling to scalar operations, which has negative impact on performance. Partially this issue was fixed in #180480, this change continues that work and implements optimized lowering for v4f16 and v8f16.
