日历的提醒内容可以根据需要修改

修改注意两方面：
1，reminder_buff 的长度：
2，显示内容：
如果需要在提醒中显示Details，请修改长度并在 mmi_tdl_entry_reminder 中添加一段代码，修改后如下：
1，reminder_buff 的长度：
#define MMI_TDL_MAX_REMINDER_NOTE_EN_SIZE     \
    (MMI_TDL_MAX_NOTE_EN_LEN + MMI_TDL_MAX_REMINDER_PREFIX_EN_LEN + MAX_TDL_LOCATION_SIZE * ENCODING_LENGTH)
2，显示内容：
void mmi_tdl_entry_reminder(void)
{
