<summary>Changes</summary>
The main goal of this PR (and subsequent PRs), is to add more tests with
scalable vectors to:
* vector-transfer-collapse-inner-most-dims.mlir
There's quite a few cases to consider, hence this is split into multiple
PRs. In this PR, `@<!-- -->outer_dyn_drop_inner_most_dim` is replaced with:
* `@<!-- -->contiguous_inner_most_dynamic_outer`
I am also adding a similar test for scalable vectors. In addition,
* `@<!-- -->drop_two_inner_most_dim` and
`@<!-- -->drop_two_inner_most_dim_scalable_inner_dim`,
are renamed as `@<!-- -->contiguous_inner_most_scalable_inner_dim` to match
their counterpart for xfer_read.
NOTE: This PR is limited to tests for `vector.transfer_write`
This is a follow-up for: #<!-- -->94490, #<!-- -->94604, #<!-- -->94906
