Code review comment for lp:~andreas-pokorny/mir/bump-graphics-platform-abi-for-0.18

Package names have been getting messy for a while now. Can we use this opportunity to improve them?...

Firstly with:
mir-platform-graphics-0.18-mesa-kms
mir-platform-graphics-0.18-mesa-x11

But also:
Can we resolve the inconsistent ordering of "plaform-graphics" vs "GRAPHICS_PLATFORM"? So that becomes:
mir-graphics-platform-0.18-mesa-kms
mir-graphics-platform-0.18-mesa-x11

And finally:
Can we abbreviate "graphics-platform" further?
