vo_opengl: support GL_EXT_texture_norm16 on GLES

This gives us 16 bit fixed-point integer texture formats, including
ability to sample from them with linear filtering, and using them as FBO
attachments.

The integer texture format path is still there for the sake of ANGLE,
which does not support GL_EXT_texture_norm16 yet.

The change to pass_dither() is needed, because the code path using
GL_R16 for the dither texture relies on glTexImage2D being able to
convert from GL_FLOAT to GL_R16. GLES does not allow this. This could be
trivially fixed by doing the conversion ourselves, but I'm too lazy to
do this now.
