Jonathan Hamilton 184e4d7b4a Fix an incorrect OES suffix on glMultiDrawElementsBaseVertex
The spec says it should have an EXT not OES suffix, as it's enabled as
an interaction with GL_EXT_multi_draw_arrays.

On some drivers GetProcAddress() returns NULL, which causes the
GLExtensions init to fail

This 'happened' to work if GetProcAddress() doesn't return NULL on missing
functions (as allowed in EGL) - as the function appears to never be called so
this would not have been noticed.

Mesa also (incorrectly?) exports the EXT version, so this would all
happen to work there, but appears to be contrary to the spec.

This invalid prefix even ended up in the upstream khronos registry, the
issue was reported here:

Stenzek c8cbbd831d GLExtensions: Seperate GL_ARB_compute_shader from GL 4.3
Allows the usage of glDispatchCompute from GLES (requires GLES 3.1).

Stenzek 4e24bfd0ce GLExtensions: Seperate GL_ARB_shader_image_load_store from GL 4.2
Allows the usage of glBindImageTexture and glMemoryBarrier from GLES
(requires GLES 3.1).

Stenzek bd15d0352a GLExtensions: Seperate GL_ARB_texture_storage from GL 4.2
This allows us to use glTexStorage on GL3.3 implementations that support
the extension.

Michael Maltese 418a7723c8 GLExtensions: remove NV_depth_buffer_float from OpenGL 3.0
Regression introduced in e99cd57 / 4935: VideoBackends: Set the maximum
range when the depth range is oversized[1]. The NV_depth_buffer_float
extension is not part of OpenGL 3.0, and requiring it causes a hard
crash when it's not supported (e.g. macOS).

Ryan Houdek 8c37498230 Fix typo in GLExtensions
I had changed a variable name and forgot to update it everywhere.
Should fix Adreno devices.

Ryan Houdek 37525f3fcf Make GLExtensions no longer require slghtly modified GL headers.
In fact, removes the need for external headers at all.

Ryan Houdek b620b26f8f [GLExtensions] Improve the extension loader.
This removes some nonsense in the extension loader where under an ES context we would still pull all function pointers and just continue onward if we
fail to pull one.
Now function pointers are only pulled if the version of GL or ES actually supports that function.
