winget should refresh the process env vars

[SteveL-MSFT]

Description of the new feature / enhancement

It's a bit annoying that after installing a package, I have to restart the shell so that PATH (or other env vars) get updated. Ideally, winget should just refresh the process env vars based on system/user env var changes.

Proposed technical implementation details

Take a look at:

• Installing a package doesn't add it it to path #549

We're looking at a few scenarios related to the path, and there is discussion and a possible workaround as well as some design work on how we might achieve this.

We're currently working on the dependency flow:

• [Dependency Issue]: Dependency can't be found by main installer after it's installed #2939

I would say this duplicates:

• Update available environment variables so the user does not need to restart their terminal #3077

Similar discussion at #222
