Fix possible EGL and GLX makeCurrent problem of GLPlatformContext and GLPlatformSurface

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Jinyoung Hur]

GLPLatformContext::makeCurrent is implemented to do no-op when it thinks there is no changes, which compares with a static storage variable, m_currentContext.
This can lead to not-working makeCurrent when other part of codes or third party library, e.g., Cairo-gl, directly change gl current context by calling something like eglMakeCurrent.

Remove [EFL] prefix. Because this patch modifies graphics and opengl. [EFL] prefix can make confusion to us.

Bug title is still confusing, it mentions EGL, but the patch also affects GLX
