configure: Let configure --enable/disable-aiglx control building of AIGLX for all DDXs

Let configure --enable/disable-aiglx control building of AIGLX for all DDXs. Currently
we can't use --enable/disable-aiglx to control if Xwin DDX is built with AIGLX enabled,
as at the moment it's forced off if we aren't building the X.Org DDX DRI or DRI2 loader

Rearrange things a bit, introducing a new automake conditional, AIGLX_DRI_LOADER to
specifically indicate if the X.Org DDX DRI/DRI2 loader convenience library should be
built, and replace the previous X.Org DDX-specific uses of the AIGLX conditional with that

As before, AIGLX_DRI_LOADER is only enabled if --enable-glx, --enable-aiglx and at least one
of --enable-dri or --enable-dri2 are enabled

This allows the general conditional AIGLX to control if AIGLX is built for the XWin DDX as
well

The C #define AIGLX set by AC_DEFINE(AIGLX) seems to be obsolete, I can't find anything
which checks it

Updated for ajax's "glx: Make --disable-dri not disable AIGLX" patch, which allows DRI2
to be enabled independently of DRI1
