Fix vertical offset for wxGTK wxStaticBox without label.

Don't use different size for the vertical border in wxStaticBox just because
it doesn't have any label, this just doesn't seem necessary and results in
different appearance for the static box with and without label.

Closes #14430.

Don't hard code horizontal border for wxStaticBox in wxGTK.

Compute the border width from the average character width instead of hard
coding it to 5 pixels. Probably doesn't make much difference in practice, but
seems to make more sense.

Create wxStaticBoxSizer elements as children of wxStaticBox in XRC.

As we now recommend creating the controls shown inside wxStaticBox as its
children, and not siblings, follow our own recommendation by doing just this
in XRC handler of wxStaticBoxSizer.

Also add a test of using a tooltip with a wxStaticBoxSizer element to the XRC
demo showing that tooltips do work now for them, unlike before.

Closes #14431.

Update debugging macros overview in the docs.

Describe how the debugging macros really work since 2.9.1, i.e. explain
wxDEBUG_LEVEL and NDEBUG instead of __WXDEBUG__.

Add wxRibbonBar::DeletePage() and ClearPages() methods.

Also add a trivial GetPageCount() helper.

Closes #14437.

Use bitmaps from resources by default in wxGTK under Windows.

Use wxBITMAP_TYPE_{BMP,CUR,ICON}_RESOURCE by default under Windows, even for
non-wxMSW ports.

Also allow loading wxImage from resources in all ports under MSW as a side
effect of this change.

Closes #14425.

Define wxEntry() with WinMain-compatible signature for all Windows ports.

Make wxEntry(HINSTANCE, ...) available in wxGTK under Windows too.

Refactor the headers to allow this and extract Windows-specific wxEntry()
declarations in wx/msw/init.h from wx/msw/app.h for consistency with the
normal wxEntry(int, char**) declared in wx/init.h.

Closes #14423.

Use wxString::t_str(), not fn_str(), with Windows API functions.

fn_str() is supposed to be used with the CRT functions taking file names only,
not Windows API functions that always take LPCTSTR with all compilers/CRT
versions.

Closes #14433.

Add a unit test verifying that wxSpinCtrl ctor doesn't generate any events.

This shouldn't happen but did (and apparently still does, sometimes) under MSW
so add a test verifying that no events are generated by the ctor.

See #14428.

Force wide char environment version initialization in wxGetEnvMap().

When using MSVC CRT, the wide character version of the environment is not
always initialized when using main() (and not _wmain()) as entry point, so
force initializing it before using _tenviron.
