Change threadx_demo to use ThreadX lib init file

Instead of using its own low level initialization file for ThreadX, the
ThreadX demo has been changed to use the one provided by the ThreadX
library.

The initialization file from the ThreadX library, assumes some specific
symbol names are present in the linker script so the script for the
Corstone-300 platform, which is the only one that currently supports the
ThreadX demo, has been updated accordingly. To still be able to use the
HardFault_Handler from the platform target, the handler provided by the
ThreadX library is marked as a weak symbol before linking.
