GRAPHICS: OPENGL: Fix shader version check discrepancy
...
We required version 110 for OpenGL backend shaders while we only checked
for version 100, although this version is not expected to work without
proper ARB extension support.
Increase minimum supported version to 1.10 which matches OpenGL 2.0

GRAPHICS: OPENGL: Allow sscanf_s for GLAD

It is properly guarded so it won't bring any portability problem and the

GRAPHICS: OPENGL: Don't try to use GLAD aliasing for shaders
...
Aliasing doesn't cover all the functions we use.
In addition, old GLSL 1.00 doesn't support the #version stance.

OPENGL: Fix GLSL version parsing
...
Some old GLES2 implementation did have a different version prefix.
Be more relax like almost everyone and look for the first digit to start
parsing.

OPENGL: Use GLAD version when available and check functions before use
...
When GLAD fails to parse version, glGetError is null and raises a
SIGSEGV.
Current version of GLAD has a bug while parsing extensions so there is a
workaround here which should disappear when it's fixed.

This avoids crashes on implementations supporting only the EXT version.
