chore(Turborepo): refactor telemetry to use turbopath (#7567)
### Description
- switch to Turbopath to handle paths, rather than strings / `fs` module
- create separate constructors that use an explicit config path vs one that uses the default
- prep for refactor to move test code into test module to better control filesystem during test execution
### Testing Instructions
Existing test suite
Closes TURBO-2495
