  [mlir][linalg] Add tests for PadOp (#110271)

Adds 3 tests for the logic to pad Linalg ops. Specifically, for
transformation under the `transform.structured.pad` TD Op.

For `@zero_pad_static` I simply took an existing test and added
check-lines. According to comments, it should fail. However, when I
tried it, it actually worked. Indeed, it triggers an important edge
cases - padding by 0 when all the shapes are static.

`@zero_pad_dynamic` exercises similar case, but some dimensions in the
input tensors are made dynamic - that's added to improve the test
coverage. Note that in this case we are padding the static dim.

Finally, `@negative_no_ub_estimate` is similar to `@zero_pad_dynamic`,
but we are trying to pad a dynamic dim instead. This fails as it's
impossible to compute the padded shape.
