renderer/native: Try 10 bpc formats for EGL surfaces

Browse Source 
For scanout on a secondary GPU, for the time being try only formats
which are guaranteed to be renderable with GLES3, which notably excludes
10 bpc formats without alpha channel.

v2:
* Use separate format array for 10 bpc formats without alpha.
