r300: fix regression from swtcl rewrite

Fix wrong attribute emit and revert to previous behaviour of calculating VAP_OUT_VTX_FMT_1 register value.

We can't use r300VAPOutputCntl1 function because it assumes that all texture coords have 4 components and that is the case for HW TCL
path, but not for SW TCL.
