In order to be used for OpenGL (right now for ARB_gl_spirv).
This commit adds two new structures:
* nir_xfb_varying_info: that identifies each individual varying. For
each one, we need to know the type, buffer and xfb_offset
* nir_xfb_buffer_info: as now for each buffer, in addition to the
stride, we need to know how many varyings are assigned to it.
For this patch, the only case where num_outputs != num_varyings is
with the case of doubles, that for dvec3/4 could require more than one
output. There are more cases though (like aoa), that will be handled
on following patches.
v2: updated after new nir general XFB support introduced for "anv: Add
support for VK_EXT_transform_feedback"
v3: compute num_varyings beforehand for allocating, instead of relying
on num_outputs as approximate value (Timothy Arceri)
