J-Link plugin thread aware debugging (issues on Windows)

Hello,

when trying to use the J-Link plugin to do thread aware debugging the JLinkGDBServer crashes/shows errors.
I compiled the plugin from master and an older version that goes along the sources I use.
master: 447a0bce958b9fca11c5505c6b6ebcd2a961d125

To compile, the MSYS2 mingw64 shell is used. I had no luck using the Makefile.host, so I ran it standalone.
Original entry
```
$(Q) $(HOSTCC) $(HOSTCFLAGS) -shared -fPIC jlink-nuttx.c -o jlink-nuttx$(HOSTDYNEXT)
```
Standalone compilation used
```
gcc -shared -fPIC jlink-nuttx.c -o jlink-nuttx.dll
```

SEGGER J-Link version used
```
SEGGER J-Link GDB Server V7.88 Command Line Version

JLinkARM.dll V7.88 (DLL compiled Apr 28 2023 08:36:41)
```

NuttX compile option used
```
CONFIG_DEBUG_TCBINFO=y
```

Target
```
STM32H743ZI
```

Output
MSYS2 MINGW64 (older sources)
```

Just to test a mingw32 build. But it doesn't match the SEGGER 64-bit tooling.
