configure: don't enable GL/X11 without X11

The OpenGL autodetection checked for all backends regardless of which
features had been enabled previously. Stop checking for X11 backend if
X11 support is disabled, and stop checking for w32 backend if we are
not on Windows.

This makes the changes in commit 3862d469ae ("configure: OSX: check
for X11 header conflict with corevideo") work as intended. That commit
disabled X11 when a header conflict was detected, but the GL X11
backend could still be autodetected despite that and trigger a
compilation failure.
