Add `sdl2.pc` pkg-config file for maximum backwards compatibility

The existing file sdl2_compat.pc contains Provides: sdl2 = 2.32.50, but this isn't recognised by all tooling. For example, to build the Haskell sdl2 and sdl2-ttf packages I've had to do sudo ln -s /usr/lib/pkgconfig/sdl2_compat.pc /usr/lib/pkgconfig/sdl2.pc.

I'll report this to Cabal, the Haskell build tool, but in the meantime perhaps we should just provide a backwards-compatible pkgconfig file? I see no real downside, and Debian already does this.

added priority3-normal severity4-low statusunconfirmed labels

assigned to @freswa, @toolybird, and @gromit

added scopeenhancement statusconfirmed labels and removed statusunconfirmed label

assigned to @svenstaro and unassigned @freswa, @toolybird, and @gromit

Sounds good. Feel like making an MR?
