Update tests to not use fixed paths in /tmp/

[asnare]

Changes

What does this PR do?

This PR updates our tests so that none of them use /tmp/ directly:

• Anything that writes to a fixed path inside /tmp/ will be flaky in the face of concurrent tests: both will attempt to modify the same path.
• Such tests do not clean up after themselves.
• Under CI/CD tests are often supposed to use a different location that /tmp/ as a work area; access may be denied.
• These tests don't work on Windows: /tmp/ does not exist

Instead tests should use the tmp_path pytest fixture to obtain a clean (and safe) temporary directory to use; it will be cleaned up when the test finishes.

To avoid confusion, unit tests that were using /tmp/ as an arbitrary path (but didn't actually access it) have been modified to use something else.

Caveats/things to watch out for when reviewing:

Some incidental changes include:

• Type hints in a few places, and using Path instead of str.
• An unused fixture was removed.
• The profiler_extract_utils module is only needed during integration tests, so it was moved to location of the integration tests.

Tests

• updated unit tests
