drivers: wifi: esp_at: fetch version of ESP-AT firmware 



For development and debugging purposes it is good to know what is the
version of ESP-AT firmware used on modem. This can be fetched with AT+GMR
command.

Fetch this information during driver init and log all available version
strings, so they look like that:

  wifi_esp_at: AT version: 2.1.0.0(883f7f2 - Jul 24 2020 11:50:07)
  wifi_esp_at: SDK version: v4.0.1-193-ge7ac221
  wifi_esp_at: compile time: (0ad6331):Jul 28 2020 02:47:21
  wifi_esp_at: Bin version: 2.1.0(WROOM-32)
