port: [#4006] Add TelemetryLoggerConstants for adaptive. (#6029)

[sw-joelmut]

Fixes #4006

Description

This PR adds the TelemetryLoggerConstants class and updates all the hard-coded string references to use the property that corresponds. These changes are ported from DotNet.

Specific Changes

• Adds the TelemetryLoggerConstants class.
• Updates all the hard-coded strings to use each specific property declared in the TelemetryLoggerConstants class, including unit tests.
• Updated the beginSkill to use the constant that corresponds with no addition of a new context property, since this case does not exist in DotNet's port.

Testing
