Generated EGL 1.5 support

After updating opengl/tools/glgen2/registry/egl.xml and gl.xml do:
cd opengl/tools/glgen
./gen
cd ../glgen2
./glgen.py

Note: Manually undo delete of glMultiDrawElementsBaseVertexOES.
EGL removed that as an API
(https://github.com/KhronosGroup/OpenGL-Registry/issues/81) but
we can't remove or we'd break backward compatibility.

Test: compile
Bug: 80239516

Change-Id: I6fa125ef076ad4ce5b53833ac6aef2f87edaf656
