Cleanup GraphicsEnv::setAngleInfo()

Cleanup some minor nits and performance issues in
GraphicsEnv::setAngleInfo():

1. Make the paramater `eglFeatures` a reference.
   * This avoids the copy of the std::vector that's currently done every
   function call.
2. Remove `std::move()` calls on `const` values.
   * std::move() has no effect on const values, resulting in a copy
     anyway.
