Time validation not working properly for languages does not have AM/PM

[ahamedalthaf]

Time formatting not working properly for languages that has different value apart from AM and PM for meridiem.

Ex:

Japanese Language:

Current:
dayjs('9:00 午後', 'h:mm A', 'ja').format('h:mm A') - 9:00 午前 (Wrong)

The value should be like below.
dayjs('9:00 午後', 'h:mm A', 'ja').format('h:mm A') - 9:00 午後 (Correct)

Information

Day.js Version: 1.11.9,
OS: MacOs

@iamkun I think the problem is in CustomParseFormat plugin. It determines afternoon by such condition https://github.com/iamkun/dayjs/blob/dev/src/plugin/customParseFormat/index.js#L55 (i > 12), but meridiem method of locale returns 12 for afternoon (https://github.com/iamkun/dayjs/blob/dev/src/locale/ja.js#L24), so we will get i === 12 and in this case this.afternoon is false.

Also there are some locales that have more than two periods, not only AM/PM, for example zh-cn, bn-bd, etc. and this method is broken for such locales.

For other locales, there is no value in between 11 and 12 so it should not be a problem. This problem will come only for three languages as of now. 'zh', 'zh-cn', 'zh-tw'
