gstgl: Re-enable WINAPI on _MSC_VER
...
The calling convention may be deprecated, but we still need it for
OpenGL. The build issue was caused by an incorrect syntax being used for
the WINAPI (__stdcall) prototype in function pointers which was accepted
by GCC but is rejected by MSVC.

glshader: add glBindFragDataLocation
...
There are some cases where it's needed for binding in/out variables in shaders.
e.g. glsl 150 (gl 3.2) doesn't support the 'layout (location = ?)' specifiers in
the shader source so we have to bind them ourselves.

GL 1.4 (with GL_ARB_shader_objects) doesn't have glIsProgram or glIsShader
equivalents. As they are simply assertions, skip them when there isn't a
valid function pointer.

gst_gl_shader_detach_unlocked already removes the list entry so attempting to
use the element to iterate to the next stage could read invalid data.
