feature: Lightweight serializer API for MQTT.
MQTT serializer API changes to support lightweight single threaded app.
CSDK MQTT Library provides stateful MQTT API that makes use of taskpool
and network abstraction. The library makes use dynamic memory
allocations and makes use of multiple threads or tasks.
Embedded applications running on microcontroller may want to
use single threaded model to run MQTT.
The API changes enable application developers to use MQTT serializer
and deserializer APIs without use of taskpool and network abstraction.
The API does no allocate any dynamic memory, therefore application can
make use of statically allocated memory. Application can implement its
own state machine and make use of any network interface like sockets
to handle MQTT messages.

* Update MQTT system tests for connection retry.
- In Amazon FreeRTOS the number of retries is set to 3.
- In the CSDK the number of retries is the default of 1,
since there are no failures in these tests' connections.
- Update doxygen for new test config IOT_TEST_MQTT_CONNECT_RETRY_COUNT
