Add Ctest support for functional testing

[oskirby]

Description

This is mostly just a minor annoyance that every time I have to run a functional test I have to remember and run a bunch of commands manually to get the functional testing envrionment setup. This makes it so that we can run a tests with something like the following:

• ctest -L functional: Run all the functional tests
• ctest -L unit: Run all the unit tests.
• ctest -L auth: Run the authentication tests.
• ctest -L qml: Run the QML tests.
• ctest -R <test name>: Run a single test.

Can you add the tag unit to mz_add_test_target aswell ? :)

Uh oh, looks like the socksproxy tests don't pass on MacOS. Guess I should fix that first.

Well we're not shipping that binary on macos, so i think you could just not compile+run the tests on macos.

👍🏻 Thanks!

This seems reasonable, though this area is not my expertise. I'd encourage waiting for at least one other approval.
