Fix def files so that the implementation agnostic interface definition has no non-standards defined entry points, and change the eglrefimpl specific implementation to place its private entry points high up in the ordinal order space in the implementation region, not the standards based entrypoints region.

Provides access to the contents of a pixel buffer. Functionality includes copying pixels into
user buffer and perform format conversion or scaling up/down. Copying can be performed
horizontally from left to right or right to left, and vertically from top to bottom or bottom
to up.
Supported buffer pixel format:
-EUidPixelFormatRGB_565
-EUidPixelFormatXRGB_8888
-EUidPixelFormatARGB_8888
-EUidPixelFormatARGB_8888_PRE
