[bug#73124] [PATCH v2 3/3] gnu: wlroots: add 0.18

[Rutherther via Guix-patches via <guix-patches@gnu.org>]

wlroots major versions are usually incompatible. With
change to 0.18 wlroots has a different .pc pkg-config file
name, wlroots-0.18.pc. That means any package using pkg-config
to search for wlroots won't be able to find it. So even if there
were no breaking changes inside wlroots code base, it means programs
cannot be compiled against different major version.

I've thus exposed every wlroots as a separate symbol without the need
for use of "wlroots" symbol, so every package can use major wlroots version
appropriate for its version. I've kept wlroots symbol to not break anything
that is currently using it for wlroots-0.17.

* gnu/packages/wm.scm: Add wlroots-0.18, bind wlroots 0.17
to wlroots-0.17 symbol to make it easier to target specific
major wlroots version.
