Ok that configuration should work.

Here on Debian bullseye:
nm -D /usr/lib/x86_64-linux-gnu/libgstgl-1.0.so.0.1602.0 | grep
gst_gl_display_wayland
00000000000440b0 T gst_gl_display_wayland_get_type
0000000000044110 T gst_gl_display_wayland_new
0000000000044220 T gst_gl_display_wayland_new_with_display
I suspect you might have gst-build libraries installed system-wide?
I would recommend to use an uninstalled setup with gst-build, using
gst-env.py.

I'm not sure what's going on there. Is this with git master? Note that
the support for software rendering in wpesrc is available only in git
master and that requires a development version of WPEBackend-FDO
(1.7.x).
Also what's the point of forcing swrast in Mesa in that pipeline?
Setting LIBGL_ALWAYS_SOFTWARE=true might have side-effects in gst-gl :)
Can you try a simpler pipeline with a non-GL sink?
LIBGL_ALWAYS_SOFTWARE=true gst-launch-1.0 wpesrc location="
https://ddg.gg" ! videoconvert ! queue ! gtksink
