feat(events): 添加事件提交函数到各个头文件中

为多个事件头文件添加了静态内联提交函数，包括：
- bat_state_event: 添加submit_bat_state_event函数
- ble_serial_rx_event: 添加submit_ble_serial_rx_event函数
- ble_serial_tx_event: 添加submit_ble_serial_tx_event函数
- cdc_proto_tx_event: 添加submit_cdc_proto_tx_event函数
- datetime_event: 添加submit_datetime_event函数
- encoder_event: 添加submit_encoder_event函数
- function_bitmap_update_event: 添加submit_function_bitmap_update_event函数
- hid_led_event: 添加submit_hid_led_event函数
- hid_report_sent_event: 添加submit_hid_report_sent_event函数
- hid_transport_state_event: 添加submit_hid_transport_state_event函数
- hid_tx_report_event: 添加submit_hid_tx_report_event函数
- key_function_event: 添加submit_key_function_event函数
- keyboard_hid_report_event: 添加submit_keyboard_hid_report_event函数
- led_strip_en_event: 添加submit_led_strip_en_event函数
- mode_switch_event: 添加submit_mode_switch_event函数
- set_protocol_event: 添加submit_set_protocol_event函数
- theme_rgb_update_event: 添加submit_theme_rgb_update_event函数
- time_sync_event: 添加submit_time_sync_event函数
- usb_cdc_rx_event: 添加submit_usb_cdc_rx_event函数
- usb_cdc_tx_event: 添加submit_usb_cdc_tx_event函数
- usb_device_state_event: 添加submit_usb_device_state_event函数
- usb_function_ready_event: 添加submit_usb_function_ready_event函数
- usb_prepare_event: 添加submit_usb_prepare_event函数

这些函数提供了一致的事件提交接口，简化了事件创建和提交过程。
