[tcat][ble] fixes to connection state mgmt and Disconnect cmd (#10619)

- Fixes to connection state management and handling of Disconnect
  command TLV
  - specifically, this now ensures that TCAT remains on (started)
    after a commissioner disconnects. Earlier, there was the problem
    that the 2nd commissioner couldn't connect anymore.
  - specifically, in ble_secure.cpp the check for if
    (mTcatAgent.IsEnabled()) is removed, since the err =
    mTcatAgent.Connected(mTls) will already check this and raise an
    error if not enabled. If not enabled, the Device is in a wrong
    state to handle TCAT Commissioner commands so now it closes the
    connection right away. That's better than to leave the
    Commissioner in limbo on the TLS connection. The Commissioner can
    now retry again and all will be well again.
- timeout of at most 10 seconds on UDP write operation in simulation
  mode (if longer, the TCAT device isn't reachable and the
  Commissioner now shows the error to the user.) Earlier, it got stuck
  forever.
- Corrects some copy/paste errors in API definitions in comments; adds
  comments where needed to explain.
  - adds whitespace at some places to align format with rest of code
- improved some of the --debug output for the UDP simulation mode of
  the TCAT Commissioner.

OpenThread Build Simulation Docker Coverage Status


What is OpenThread?

OpenThread released by Google is...

...an open-source implementation of the Thread networking protocol. Google Nest has released OpenThread to make the technology used in Nest products more broadly available to developers to accelerate the development of products for the connected home.

...OS and platform agnostic, with a narrow platform abstraction layer and a small memory footprint, making it highly portable. It supports both system-on-chip (SoC) and network co-processor (NCP) designs.

...a Thread Certified Component, implementing all features defined in the Thread 1.3.0 specification, including all Thread networking layers (IPv6, 6LoWPAN, IEEE 802.15.4 with MAC security, Mesh Link Establishment, Mesh Routing) and device roles, as well as Border Router support.
