8569296384 OPENGL: Detect framebuffer support using GL_ARB_framebuffer_object 
We use functions from GL_ARB_framebuffer_object extension and not from
GL_EXT_framebuffer_object where functions are suffixed by EXT.
This avoids crashes on implementations supporting only the EXT version.

c9b4949746 AMIGAOS: Improve shader compatibility 
OGLES2 doesn't support uniform booleans so we use macros to make it use
integers in this case. For other platforms, this change should be a
noop.
OGLES2 doesn't like float suffix for constants, remove it as well.

fd129ebc0c JANITORIAL: "Mac OS X" and "OS X" to "macOS" in comments 
Apple's desktop operating system was formerly called "Mac OS X" and "OS X", but since 2016 it has been called "macOS" (starting with version 10.12).

Changing across all comments and documentation to use this current terminology, except in cases where the historical versions are explicitly referenced. No code changes are made; we should consider changing those in future PRs.

a9418f8f63 GRAPHICS: Rework OpenGL detection 
With GLAD it's not needed anymore to link against OpenGL libraries.
As configure knows better whether a platform supports GLAD, detection is
moved here.
To allow platforms where OpenGL should be linked at build time, the
tests are kept. Android uses them for now.
The OpenGL for Games was completely decoupled from the OpenGL for 2D
engines. This not the case anymore.
