tgt-vvp: Remove unused draw_eval_bool64() 

Ever since the conversion to use a stack for vectors `draw_eval_bool64()`
has been unused. The last caller of `draw_eval_bool64()` was removed in
commit e4b862f3d1 ("Clean up vector handling dead code.").

Remove `draw_eval_bool64()` and related functions as well.
