egl: implement eglQueryDmaBufModifiersEXT
query and return supported dmabuf format modifiers for
EGL_EXT_image_dma_buf_import_modifiers.
v2: move format check to the driver instead of making format queries
here and then checking.
v3: Check DRIimageExtension version before query (Daniel Stone)
v4:
- move to DRIimageExtension version 15, check queryDmaBufModifiers before
calling (Jason Ekstrand)
- pass external_only to the driver instead of setting as EGL_TRUE here
