Feature request: Add support for both X/Y mirror in footprint editor

Description

There is a mirror option when right clicked on any object in Footprint Editor. But the issue is, it does not allow to select the axis to which mirror will be performed. Currently it performs mirror along vertical axis only.

Just like Schematic Editor, There should be option to mirror horizontally or vertically.

Steps to reproduce

1. Open any footprint in the Footprint Editor.
2. Select any object like silkscreen line/polygon or pad etc.
3. Right click and mirror
