[Status Bar] Implement per-rotation bottom aligned margin configuration
This allows to have bottom aligned status bar content. Will be used when
the content shouldn't be centered vertically within the status bar.
A bottom margin of 0 means that the content will be aligned to the
bottom of the status bar.
A bottom margin of < 0 means that the value will be ignored, and that
the content will be centered vertically.
