Revert "nv50,nvc0: remove bogus 64_FLOAT formats"

This reverts commit 20346808cf4f1ee4f320afaf18f94043fb146f2e.

The conversion is actually done since these are the *B macro variants
and no vtx format is supplied, which makes them go through the translate
module.

This restores the following piglit tests to passing:

  draw-vertices user
  gl-2.0-vertexattribpointer
