DevTools: test migration cleanup - remove LayoutTests/http/tests/inspector

Now that all the tests have been migrated to the new integration test
framework, we can remove the remaining bits of the legacy framework.

There were a few references to inspector files in a handful of network
tests, which have been updated to their respective devtools' resources files.

Also found a (disabled) virtual test that slipped through the cracks:
virtual/threaded/http/tests/devtools/tracing/idle-callback.js
