test(util): port remaining todo!() tests in util test suite

Implement previously-todo!() tests in auth_helper_test.rs,
process_executor_test.rs, remote_filesystem_test.rs, and
stream_context_factory_test.rs by porting the corresponding PHPUnit
test methods. Extend IOStub with writeRaw/setAuthentication call
tracking and askAndValidate/getAuthentication overrides to model the
PHPUnit mocks these tests rely on, deduping the resulting
call-recording fields into a small generic CallRecorder<T> helper
instead of repeating the same RefCell<Vec<T>> push/borrow().clone()
boilerplate five times.

testStoreAuthWithPromptInvalidAnswer and
testPromptAuthIfNeededMultipleBitbucketDownloads had initially lost
the ported PHPUnit mock's argument/call-count assertions
(askAndValidate's exact prompt string, and
hasAuthentication/getAuthentication's exactly(2) call counts),
silently narrowing what the tests verify; IOStub now records these
calls and the tests assert on them, matching upstream.

Tests left unportable (PHP set_error_handler machinery, closures in
data providers, network/subclass-mock dependencies, etc.) keep
#[ignore] with a single // TODO(phase-d) reason recorded in the
function body.
