Resolves#101708
The updated logic now correctly checks if `transfer_write` completely
overwrites `insert_slice` and only then applies the rewrite for this
pattern.
This check currently covers static sizes, for dynamic sizes
value bounds analysis is needed (see `TODO:`).
Remove patterns that fold tensor subset ops into vector transfer ops from the vector dialect. These patterns already exist in the tensor dialect.

These patterns follow FoldMemRefAliasOps which is further refactored for reuse.
In the process, fix FoldMemRefAliasOps handling of strides for vector.transfer ops which was previously incorrect.
These opt-in patterns generalize the existing canonicalizations on vector.transfer ops.
In the future the blanket canonicalizations will be retired.
They are kept for now to minimize porting disruptions.
