DisplayRenderer uses DisplayColorSpace to get suitable output
buffer format for Reshape(). However, Wayland didn't set that
and default value (RBGA_8888) was used instead. This didn't
work well as Wayland may have crashed because this specific
buffer format wasn't supported.

My observation showed that Chromium supports either BGRA_8888 or
RGBA_8888 as default buffer formats. Thus, figure out, which
of them is supported and use that when creating Display.

This fixes a crash that results in the following error -
wl_display@1.error(zwp_linux_buffer_params_v1@16, 7, "failed to import supplied dmabufs: Unsupported buffer format 875708993")
