Always build absolute paths the same way

Fix a bug where output paths like:

C:\foo\bar

triggered bad logic to detect relative paths and turned the path into

.\C:\foo\bar

Fix this by moving absolute path detection logic into a common helper
function and calling it consistently.

Bug: 29091703
Test: unittests, angler-eng builds with this change, manual testing on
      windows demonstrates issue is fixed
