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.
