[WPE] WPE Platform: use gbm_import_fd_modifier_data in
WPEBufferDMABuf.import_to_pixels
https://bugs.webkit.org/show_bug.cgi?id=299575
Reviewed by Carlos Garcia Campos.
GBM offers the struct gbm_import_fd_modifier_data that we can use with
gbm_bo_import to let it know more details about the format of the
buffer, like modifier flags and multiple planes. Using it allows to
read pixels from non-linear (e.g. tiled ) or multi-planar buffers,
leaving only the pixel format as the only remaining constraint.
Also, we don't need to pass the GBM_BO_USE_RENDERING and
GBM_BO_USE_LINEAR flags to gbm_bo_import, as they're relevant only when
creating BO instances. In fact, gbm_bo_map already "exposes a linear
view of the buffer even if the buffer has a non-linear modifier".
