  [mlir][Vector] Handle 0-rank case in fold instead of RewriterPattern (#130168)

For vector.extract, the folder always canonicalizes to a vector.extract
operation, while the rewrite pattern canonicalizes to a vector.broadcast
except in the case of 0-rank vectors.

Remove this special casing, and instead handle the 0-rank vector case in
the folder.
