[ESP32] Use absolute paths in example's CMakeLists.txt files

[shubhamdp]

Problem

• Few paths in examples' CMakeLists.txt files uses relative paths. If esp32 application is moved to some other path other than examples/some-app/esp32 then build would fail.

Change overview

• Use absolute path by using third_party/connectedhomeip symbolic link.

Testing

• Manually built all-clusters-app/esp32 with default configuration
• Manually built all-clusters-app/esp32 by enabling pw rpc, CONFIG_ENABLE_PW_RPC
• CI pipeline must be green
