  [mlir][vector] Address linearization comments (post commit) (#138075)

This PR adds some documentation to address comments in
https://github.com/llvm/llvm-project/pull/136581 

This PR adds a test for linearization across scf.for. This new test
might be considered redundant by more experienced MLIRers, but might
help newer users understand how to linearize scf/cf/func operations
easily

The documentation added in this PR also tightens our definition of
linearization, to now exclude unrolling (which creates multiple ops from
1 op). We hadn't really specified what linearization meant before.
