[mlir][vector] Standardise `valueToStore` Naming Across Vector Ops (NFC) (#134206)

This change standardises the naming convention for the argument
representing the value to store in various vector operations.
Specifically, it ensures that all vector ops storing a value—whether
into memory, a tensor, or another vector — use `valueToStore` for the
corresponding argument name.

Updated operations:
* `vector.transfer_write`, `vector.insert`, `vector.scalable_insert`,
  `vector.insert_strided_slice`.

For reference, here are operations that currently use `valueToStore`:
* `vector.store` `vector.scatter`, `vector.compressstore`,
  `vector.maskedstore`.

This change is non-functional (NFC) and does not affect the
functionality of these operations.

Implements #131602
