From: Varad Gautam <varad.gau...@collabora.com>
format modifiers tokens are driver specific, and hence, need to come
in from the driver. this allows drivers to be queried for supported
format modifiers for EGL_EXT_image_dma_buf_import_modifiers.
v2: rebase to master.
v3: drivers must return false on query failure.
v4: use pscreen->is_format_supported instead of adding a separate
format query handle, remove PIPE_CAP_QUERY_DMABUF_ATTRIBS.
