GDB ThreadX aware plugin

[alobop]

Is your feature request related to a problem? Please describe.
GDB debugging is possible with ThreadX, but there are no official plugins that allow support for OS aware features such as enumerating threads and switching context in the debugger.

Describe the solution you'd like
A plugin that can be loaded by GDB to provide OS awareness, such as it supports info threads and related commands,

Describe alternatives you've considered
GDB scripting over the threadx structs.

well, for me, ThreadX debugging worked good, with enumerating threads and switching context through GDB, just in OpenOCD I configured it, and it works perfectly. https://openocd.org/doc/html/GDB-and-OpenOCD.html#RTOS-Support
