configure.ac: add an enable switch for float textures (v2)
So --enable-texture-float it is.
Hardware drivers (including the Gallium ones) should
use #ifdef TEXTURE_FLOAT_ENABLED to hide any code that may
expose floating-point renderbuffers via any interface,
public or private.
v2: Print a warning when using --enable-texture-float.
