1692896e5e mesh: add channel switch function
1. add network channel switch function.
   - users can obtain the new channel through the event MESH_EVENT_CHANNEL_SWITCH.
   - the entire network will be moved to the same channel as the router without user intervention.
   - if no router is in the network, users can call esp_mesh_switch_channel() on the root side to
     move the entire network to their desired channel.
2. support not configuring the network channel.
3. support not configuring the router BSSID even if the router is hidden.
4. add allow_channel_switch to mesh configuration.
   - if the channel is not specified, this value will be ignored.
   - if the channel is specified and this value is set, when "fail" (mesh_attempts_t) times of parent selection
     or look for networks are reached, device will change to perform a full channel scan for networks that could join.
   - if the channel is specified and this value is set to 0, when a root is not elected, channel switch is not allowed.
     but when a root appears, the root performs a full channel scan during the process of connecting to the router,
     so even allow_channel_switch is set to 0, the root may still switch channel and eventually the entire network
    changes channel.
5. add allow_router_switch to mesh router configuration.
   - if the BSSID of router is not specified, this value will be ignored.
   - if the BSSID of router is specified and this value is set, when the router of this specified BSSID fails to be found
     after "fail" (mesh_attempts_t) times, the entire network is allowed to switch to another router with the same SSID.
6. modify the root to perform a full channel scan when esp_wifi_connect().
7. support handling beacon without DS Paramter Set.

6c3b5ae5a1 mesh: bugfix
1. fix failture of mesh stop caused by block-sending.
2. fix when FIXED_ROOT is set, 2nd layer devices can not receive mesh event ESP_ERR_MESH_NO_PARENT_FOUND.
3. fix when FIXED_ROOT is set and the root turns off mesh function, 2nd layer devices do not look for new parents.
4. add APIs esp_mesh_disconnect() and esp_mesh_connect().
5. disconnect from parent/router when the DSSS channel in received beacon is different from the home channel.
6. remove nvs task to release 3k bytes memory.

2d34a93dc4 mesh: update libs
1. fix ap_loss that occurs when the parent turns off the mesh function and becomes a normal WiFi with a different SSID.
2. add an event MESH_EVENT_NETWORK_STATE that contains information about whether there is a root in the current network.
3. modify the mechanism of mesh IE update.
4. fix a problem in the process of re-voting to select the root, the device that does not meet the conditions of being a root votes for itself.
5. fix an issue that occurs in esp_mesh_recv_toDS() when stopping the mesh.
6. when the user specifies a parent for the device, the device will set the authmode and password of its AP mode to the same value as the specified parent.
7. add two disconnected reason codes MESH_REASON_EMPTY_PASSWORD and MESH_REASON_PARENT_UNENCRYPTED.

2. support modify parent at any time after mesh is configured.
3. modify manual networking example.
4. update header file.
5. fix issues in root conflicts handling.
6. add max length of beacon to menuconfig.
7. fix issue when received a beacon without DSSS.
