Make wxToolBar styles consistent and add wxTB_DEFAULT_STYLE.

Don't include wxBORDER_NONE in neither wxToolBar ctor and Create() nor
wxFrame::CreateToolBar() flags parameter, override GetDefaultBorder() in
wxToolBar itself instead to use the border style appropriate for the current
platform by default. This has the same effect -- the default border style is
used unless another one is explicitly specified -- but is more clear and
consistent.

Also add wxTB_DEFAULT_STYLE for consistency with the other classes.

Closes #15037.
