CMake: update backend selection

The single DAWN_ENABLE_OPENGL flag in the root CMakeLists.txt did not define
DAWN_ENABLE_BACKEND_DESKTOP_GL or DAWN_ENABLE_BACKEND_OPENGLES, so examples
with `-b opengl` reported `Backend isn't present` and failed to start.

ENABLE_OPENGL flag in root CMakeLists.txt was replaced by ENABLE_DESKTOP_GL
and ENABLE_OPENGLES flags, repeating the logic of similar flags
in GN buildsystem as done in src/common/BUILD.gn
and scripts/dawn_features.gni.
