Revert "wegl: add EGL image create/destroy"
This reverts commit
1a8e8ef3b8072fa1135dbe2a04dc6bb9f8e3a12f.
The symbols were added as they are required by the null/surfaceless
platform. Since that one hasn't landed yet, just remove the patch.
Furthermore, using dlsym is non-compatible (according to the spec) since
the symbols are part of an extension. eglGetProcAddress should be used.
Feel free to bring it back, when needed.
