added cpu architecture and default environment in profiles envelope

[stefanosiano]

📜 Description

Added cpu architecture in profiles envelope payload
Profiles environment defaults to "production"

💡 Motivation and Context

• cpu architecture was requested to be added to the profiles data.
• We found that profiles didn't have any environment, even if the transaction had one set. I figured out it was set in the transaction in the MainProcessor in case it's null, so i added the same logic to the profiles, too.

💚 How did you test it?

I added assertions on these fields to the ui test that sends a profile envelope
