EGLNativeWindowType can be aliased to a different type depending on the
EGL implementation headers, and static_cast (or reinterpret_cast) may
not always work. This is similar to 194561 at main, but with the conversion
being done in the opposite direction, therefore we apply the same
solution using a C style cast expression, which works in all cases.

For the build failures related to the usage of OpenGL ES 3 symbols, add
the needed HAVE(OPENGL_3_ES) guards and avoid using GL_MAJOR_VERSION
and instead parse the GL_VERSION string in a way similar as in the
GLContext::version() function.

* Source/WebCore/platform/graphics/egl/GLContextEGL.cpp:
(WebCore::GLContextEGL::createWindowContext): Use a plain C cast expression.
* Source/WebCore/platform/graphics/opengl/ExtensionsGLOpenGLES.cpp:
(WebCore::ExtensionsGLOpenGLES::platformSupportsExtension): Apply
HAVE(OPENGL_3_ES) guards, avoid using GL_MAJOR_VERSION.
