Fix flickering of wxStaticBox background in wxMSW.

First of all, don't erase background in WM_ERASEBKGND at all if we erase it
anyhow in WM_PAINT, this is totally useless and is what wxBG_STYLE_PAINT is for.

Second, clip out not only the siblings of the static box but also its children
when erasing the background to avoid painting over the controls created as the
box children, which is the preferred way to create them now.

Closes #15150.

Make wxMSW stack walking methods work with Unicode identifiers.

This allows to show the stack properly for e.g. Japanese programs.

Closes #15138.

Revert "Make wxMSW stack walking methods work with Unicode identifiers."

This reverts r74817 because it broke compilation with VC8 and it doesn't seem
obvious to fix this.

See #15138, closes #15500.
