Provide the ability to reserve instance names and provide + reserve definition names

[mkorbel1]

Description & Motivation

• There are some situations where it is desirable for Module instance names to be fixed and not uniquified. A new flag in Module provides the ability to prevent an instance name from being uniquified.
• There are some situations where it is desirable for Module definition names to be set in generated output. A new String parameter enables users to specify the desired definition name. It can be reserved as well via flag, similar to the new capability for instance names.
