[Android] Use ms for number report

[kirklandsign]

ns * 1e-6 = ms

Example output:
(9.36ms inference mv2_xnnpack)

[{"actualValue":9.3611927,"benchmarkModel":{"backend":"","name":"mv2_xnnpack","quantization":""},"deviceInfo":{"arch":"SM-S926U1","availMem":0,"device":"samsung","os":"Android 14","totalMem":0},"metric":"avg_inference_latency(ms)","targetValue":0.0},{"actualValue":27.418698,"benchmarkModel":{"backend":"","name":"mv2_xnnpack","quantization":""},"deviceInfo":{"arch":"SM-S926U1","availMem":0,"device":"samsung","os":"Android 14","totalMem":0},"metric":"model_load_time(ms)","targetValue":0.0},{"actualValue":0.0,"benchmarkModel":{"backend":"","name":"mv2_xnnpack","quantization":""},"deviceInfo":{"arch":"SM-S926U1","availMem":0,"device":"samsung","os":"Android 14","totalMem":0},"metric":"load_status","targetValue":0.0}]

and for LLM
(12.34 tps mocked number)

still ns?

[huydhn]

Nit: The metric value is now in (ms) instead of (ns), so its name need to be updated accordingly

[huydhn]
