Add condition for Matmul and Select in ClampFP16OutputSoftmaxMatcher (#31798)
### Description of the issue
- symptom: audio output file is invalid. (Empty audio file) Output file
of fp32 inference sounds fine.
- root-cause: Matmul layer generated 'inf' value to output

ACTIVATIONS_SCALE_FACTOR did not work for this case.
- how resolved:
Add matching case of Select layer to a matcher of
ClampFP16OutputSoftmaxMatcher to prevent 'inf' value propagated through
softmax
#### The code and line that caused this issue
- Accuracy issue : Missing logic to prevent 'inf' value passed to
softmax
#### Reproduction step and snapshot
- Execute openvino notebooks/openvoice2-and-melotts
#### Checklist
- [x] Is it a proper fix? (not a workaround)
- [x] Did you include test case for this fix, if necessary?
- [x] Did you review existing test that can be extended to cover this
scenario? Which test did you review? : reviewed unittests with
"ClampFp16OutputTest"
