--gtest_list_tests prints incorrect test names

### Describe the issue

Output from `testsuite --gtest_list_tests` is structured by test suites, listing test names with indentation. This makes it impossible to compose a filter for the option `--gtest_filter`, because the precise test name is never printed, whereas incorrect (and therefore useless) test names are printed instead. Correct behavior would print the exact test name adjacent to each test, in the precise format that will match that test when using option `--gtest_filter`. This kind of problem is widely known as the "needle in a haystack design error" because the design forces users into an unproductive trial-and-error game of guessing an internal representation that cannot be discovered any easier way.

### Steps to reproduce the problem

Invoke `testsuite --gtest_list_tests` on any gtest suite.

### Additional context

_No response_

Start by running `testsuite --gtest_list_tests` and compare its output with the names accepted by `--gtest_filter`. Trace the list-tests entry point and determine the exact name format expected by the filter; done means every listed test displays a directly usable filter name.
