(maint) Fix incorrect naming style uses

Description Of Changes

A while back we started implementing a standard of the naming style
that is meant to be followed in the repository.
At that time not everything was renamed to follow this new naming style,
and this change attempts to update all remaining items that hadn't been
renamed.

Motivation and Context

To be consistent across the entire codebase.
