Validate DynamicQuantizeLSTM recurrence quantization parameter shapes (#29254)
### Description
The `R_zero_point` / `R_scale` (recurrence) quantization-parameter shape
validation in `DynamicQuantizeLSTM` was inadvertently checking the `W`
(input) quantization parameters instead of the `R` ones. This change
validates the `R` parameters' own shapes symmetrically with `W`, so
malformed recurrence quantization parameters are rejected with a clear
error.
### Changes
- Fix the shape checks so `R_zero_point` and `R_scale` are validated
against the `R` tensor's expected shape (previously bound to the `W`
tensor).
- Add two expect-failure unit tests covering inconsistent recurrence
zero-point and scale shapes.
### Motivation
Improves input validation and error diagnostics for malformed
`DynamicQuantizeLSTM` recurrence quantization parameters. CPU-only; no
behavior change for valid inputs.
