Use CALayer instead of NSView for EGLNativeWindowType

Browse Source 
The only two EGL implementations on macOS are Swiftshader and ANGLE.
While Swiftshader supports both `NSView` and `CALayer` as
`EGLNativeWindowType`, ANGLE supports only `CALayer`. Furthermore
Swiftshader's OpenGL ES frontend is deprecated in favor of using ANGLE's
Vulkan backend on top of Swiftshader's Vulkan frontend.

This means that on macOS `EGLNativeWindowType` should be a `CALayer` for
compatibility with ANGLE.

Fixes #1169.
Closes #1680.
