Merge remote-tracking branch 'upstream/main' into HEAD

Revert "Update config.mk"

This reverts commit 7d2415bfe854cccc2bcf2709fecc1eaacddbe903.

Will stick with wlroots 0.19 for now.

Update config.mk

compiles and works fine on wlroots-0.20

Cleanup comments

reorder config.mk variables

By placing the default WLR_INCS and WLR_LIBS before the ones for an
alternative wlroots, they don't need to be commented to enable the
alternative ones.

allow the use of non-system wlroots library
