egl: implement EXT_surface_SMPTE2086_metadata and EXT_surface_CTA861_3_metadata

Patch implements common bits for EXT_surface_SMPTE2086_metadata
and EXT_surface_CTA861_3_metadata extensions by adding new required
attributes and eglQuerySurface + eglSurfaceAttrib changes.

Currently none of the drivers are utilizing this data but this patch
is enabler in getting there.

v2: don't enable extension globally, should be only enabled by
    EGL drivers that can transfer metadata to the window system (Jason)
    use EGLint instead of uint16_t (Eric)
