TF_SelectV2Op gets legalized to TFL_SelectOp

[gaikwadrahul8]

1. System information

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Ubuntu 22.04
• TensorFlow installation (pip package or built from source): pip package
• TensorFlow library (version, if pip package or github SHA, if built from source): v2.17.0

2. Code

tf.where(condition, x, y)

3. Failure after conversion

The model cannot run on TFLite Micro, as it doesn't support the old SELECT op, only the new SELECT_V2 one.

5. (optional) Any other info / logs

The change was introduced 5 years ago by @abattery to improve compatibility with the older runtimes: tensorflow/tensorflow@061d2e0
But now it breaks compatibility with TFLite Micro, which only supports the newer op.
Here's the legalization in question: https://github.com/tensorflow/tensorflow/blob/master/tensorflow/compiler/mlir/lite/transforms/legalize_patterns.td#L302
UPD: I believe that #93 is basically the same.
