vcl: introduce a BitmapEx::DumpAsPng()
This is mostly useful for ad-hoc debugging, so you don't need to
manually create an SvFileStream, a vcl::PngImageWriter & connect them,
but you can step through code in the debugger and call DumpAsPng() at
random code locations.
The filename type is intentionally a 'const char*', so you can call
DumpAsPng(0) from gdb; that would not be possible for a 'const
OUString&' parameter type.
