Increment version to 1.24-Update3 for Linux and update Release Notes

* Revert "Linux: Fix failure to run VeraCrypt binary built for console mode on headless machines (fix issue https://github.com/veracrypt/VeraCrypt/issues/531)"

The build failure still exists for system wxGTK compiled with '--disable-gui':

```
In file included from TextUserInterface.cpp:27:
TextUserInterface.h: In member function ‘virtual bool VeraCrypt::TextUserInterface::Initialize(int&, wxChar**)’:
TextUserInterface.h:50:63: error: ‘wxAppBase’ has not been declared
   50 |   virtual bool Initialize (int &argc, wxChar **argv) { return wxAppBase::Initialize(argc, argv); }
```

This reverts commit 737e1f126b.

* Revert "Linux: fix compilation error when building console-only version of VeraCrypt that is statically linked to wxWidgets"

The build failure still exists for system wxGTK compiled with '--disable-gui':

```
In file included from TextUserInterface.cpp:27:
TextUserInterface.h: In member function ‘virtual bool VeraCrypt::TextUserInterface::Initialize(int&, wxChar**)’:
TextUserInterface.h:50:63: error: ‘wxAppBase’ has not been declared
   50 |   virtual bool Initialize (int &argc, wxChar **argv) { return wxAppBase::Initialize(argc, argv); }
```

This reverts commit 14bee5e6a2.

* src/Main/Main.make: simplify the WX_CONFIG_LIBS logic

Irrespective of whether we are linking against widgets statically or
dynamically, pull in only 'base' when GUI is disabled, and
'adv,core,base' when GUI is enabled. When GUI is disabled, the C/CXX
flag must include '-DwxUSE_GUI=0' for this to work.

* src/Makefile: pass '-DwxUSE_GUI=0' when NOGUI=1

veracrypt with NOGUI=1 fails to properly link against wxGTK compiled
with '--disable-gui' only using the 'base' library because the wx's
setup.h implicitly defines wxUSE_GUI=1, which then changes the
definition of various structures, requiring symbols from the core
library as well.

For example, wxwidgets include/wx/app.h defines:

  #if wxUSE_GUI

  class WXDLLIMPEXP_CORE wxAppBase : public wxAppConsole
  ...
  [snip]
  ...
  #else // !GUI

  // wxApp is defined in core and we cannot define another one in wxBase,
  // so use the preprocessor to allow using wxApp in console programs too
  #define wxApp wxAppConsole

  #endif // GUI/!GUI

To fix this, pass '-DwxUSE_GUI=0' when compiling veracrypt with
NOGUI=1.
