vrend,caps: Move all v2 caps into according function (v4)

Move all v2 caps into the caps_v2 function that also gets renamed.
Protect the GL only value queries by using the according gl_ver test.

(Part two of cleanup suggested by Gurchetan)

v4: rebase after image support and compute shader patches landed
v5: use basic check for GL for GL_SMOOTH_*_SIZE_RANGE  (Erik)
