* Replace library links with the application-protocols one
The ReadMe.txt refers to library link on FreeRTOS.org which will not be available until after the library is released in github. Instead, use top level page https://www.freertos.org/application-protocols.html which lists all the libraries in this directory which is also easy for user to navigate and could avoid this issue when releasing new library.

* Remove submodules of community and partner contribution repos, and stale directory of FreeRTOS+UDP
* Obselete NTP demo and rename of HTTP server demo folder
* Update manifest.yml
Since `mbedtls_error.c` is already part of the mbedTLS submodule, the duplicate files are removed from this repository.

Update the coreSNTP submodule to the latest commit. Also, make updates to the coreSNTP demo for the new changes in the SNTP library which include the following:
1. Update to the type for packet size from size_t to uint16_t for parameters in the transport and authentication interfaces.
2. Change in the call to Sntp_SendTimeRequest API to pass the new blockTimeMs parameter added to the API.
3. Update to the clock-offfset type from int32_t to int64_t for representing information in milliseconds. To accommodate this update in the SntpSetTime_t interface, the mathematical model for representing system clock has been updated to store slew rate as milliseconds/second (instead of second/second). This change improves the accuracy of the WinSim demo time correction (because the milliseconds of time difference between server and client time is corrected over the entire polling interval which makes a significant difference!).
This PR also adds demo config macros for setting the block time values passed to the Sntp_SendTimeRequest and Sntp_ReceiveTimeResponse APIs.
Add the FreeRTOS/coreSNTP library as a submodule (along with manifest.yaml file update) and add a demo project to showcase use of the coreSNTP library for having a SNTP client daemon in the system for periodically synchronizing system time with the internet to maintain Coordinated Univeral Time (UTC) in a device. This demo maintains UTC time of system in RAM, thereby, representing systems without a Real-Time Clock (RTC) module in the device.
Note: This demo shows use of coreSNTP library for SNTP communication with NTP/SNTP time servers in non-authenticated mode (i.e. without any security mechanism payload beyond the standard 48 bytes of NTP packet exchange between client-server).

FreeRTOS_send adds the packet to be sent to the IP task's queue for
later processing. The packet is sent later by the IP task. When
FreeRTOS is used in collaborative mode (i.e. configUSE_PREEMPTION is 0),
the Plaintext_FreeRTOS_send function returns without actually sending
the packet as the IP task never gets a chance to run.
The fact that Plaintext_FreeRTOS_send returns without actually sending
the packet causes an issue in the MQTT_Connect which expects the CONNECT
packet to be actually sent and waits for CONNACK.
This commit adds a taskYIELD call after calling FreeRTOS_send to ensure
that the IP task gets a chance to run and send the packet before the
Plaintext_FreeRTOS_send function returns.
Add URL file links to the MQTT agent documentation page.
Add comment blocks into each demo that also point toward the MQTT agent documentation to ensure users are aware the agent method exists.
From the FreeRTOS documentation, pdFREERTOS_ERRNO_ENOSPC means that timeout occurred before any data could be sent or received.
- In the plaintext transport-interface implementation, we would directly return `-pdFREERTOS_ERRNO_ENOSPC`. However, an error like this can occur when the TCP buffer is full, so this ought to be retriable. Libraries that consume the transport interface interpret a return value of 0 to mean that send/recv can be invoked again to get the data. As such, we should appropriately set the return value as 0 when the status is `-pdFREERTOS_ERRNO_ENOSPC`.
- In the mbedTLS port, we would directly return whatever `FreeRTOS_send` or `FreeRTOS_recv` returns. However, sometimes, the return value can be an error. In such cases, we ought to map an error from FreeRTOS+TCP to an equivalent error in mbedTLS. In the case of `-pdFREERTOS_ERRNO_ENOSPC`, we map that to `MBEDTLS_ERR_SSL_TIMEOUT`. When the mbedTLS transport-interface send/recv wrapper sees that value, it appropriately returns 0, so that the library can retry the send/recv. I've verified that when the mbedTLS port returns an error, that same error is returned by `mbedtls_ssl_write` & `mbedtls_ssl_read`.
- The TCP socket may have a receive block time. If bytesToRecv is greater than 1 then a frame is likely already part way through reception and blocking to wait for the desired number of bytes to be available is the
most efficient thing to do. If bytesToRecv is 1 then this may be a speculative call to read to find the start of a new frame, in which case blocking is not desirable as it could block an entire protocol agent task for the duration of the read block time and therefore negatively impact performance. So if bytesToRecv is 1 then don't call recv unless it is known that bytes are already available.

The MQTT library has been updated with the MQTT_RECV_POLLING_TIMEOUT_MS and MQTT_SEND_RETRY_TIMEOUT_MS configurations which should be set to zero when using a dummy timer function to avoid possibility of infinite loop when retrying failed transport send/receive calls. As the MQTT Keep Alive demo uses a dummy timer function, this PR updates the demo configuration to set these timeouts to zero.
The FreeRTOS+TCP submodule pointer was set to a commit not in main,
which also lacked commits in main, which ended up causing build failures
for defender demo.
