Examples do not work on newer versions of macOS

[azeey]

Environment

• OS Version: macOS Ventura
• Source or binary build? any

Description

• Expected behavior: Examples would compile and run successfully
• Actual behavior: As mentioned in gz-rendering: Bounding Box camera gazebo_test_cases#672, examples fail with

UNSUPPORTED (log once): gldCopyBufferSubData: NEEDS IMPLEMENTATION
libc++abi: terminating due to uncaught exception of type Ogre::RenderingAPIException: OGRE EXCEPTION(3:RenderingAPIException): Fragment Program Ogre/DPSM/CubeToDpsm_ps_GLSL failed to compile. See compile log above for details. in GLSLShader::compile at /tmp/ogre2.3-20230526-26210-1dj9624/ogre-next-2.3.1/RenderSystems/GL3Plus/src/GLSL/OgreGLSLShader.cpp (line 364)

Also, the fact that almost all of the examples use OpenGL and GLUT may be problematic on macOS.

in many of the examples, users can specify to use metal as the graphics rendering API and it should work. For the bounding box camera example, we'll need to extend it to take the metal arg like what's done in other examples
