`wifi_prov_mgr_is_provisioned()` API uses the `esp_wifi_get_config()` API
to check if Wi-Fi credentials are configured. It does not really require
any other information from the wifi_prov component. Hence, this commit
removed dependency of this API on provisioning manager initialization state.
Closes IDF-5878
1) Rename srp component to esp_srp
2) Remove dependency on hkdf sha
3) Restructure protocomm component APIs to make them more flexible for allowing multiple security versions
4) esp_srp: convert API return type from int to esp_err_t
5) esp_srp: Formatting changes
6) Added mbedtls_gcm instead of aes_ctr
