gnu: dear-imgui: Delete package, preferring the newer 'imgui'.

Commit 1a4cc954d2fcea172a450ae03419b7fdda28b81e added imgui, without noticing
about the pre-existing 'dear-imgui' package.

* gnu/packages/graphics.scm (dear-imgui): Delete variable, but salvage the
superior synopsis and description to...
* gnu/packages/toolkits.scm (imgui): ... here.
