Remove Unnecessary List Conversions in Input Validation

[allrob23]

Description

This PR simplifies the code by removing unnecessary list() calls around .keys() in the _validate_input method calls. The dict_keys views are already iterable and support membership testing, so converting them to a list and then searching within that list in the function is not needed. This change makes the code cleaner and provides a small optimization by avoiding the list conversion.

Changes:

• Updated three calls to _validate_input to pass input_feed.keys() and input_dict_ort_values.keys() directly instead of wrapping them with list().

Motivation and Context

This cleans up the code and avoids an extra step that doesn’t add value. It’s a small improvement, not tied to fixing a specific issue, just making the code simpler and slightly more efficient.

No open issues are linked—this is just a minor cleanup.
