Bug: `cc_test` can't be used in `test_action`

Describe the bug

Envoy Mobile's C++ tests fail to generate due to this internal assertion failure:

ERROR: Internal precondition failure:
An `XCSchemeInfo.TestActionInfo` should only contain testable `XCSchemeInfo.TargetInfo` values.

Reproduction steps

git clone https://github.com/jpsim/envoy.git
cd envoy
git checkout jp-rules_xcodeproj-cpp
cd mobile
./bazelw run xcodeproj

Expected behavior

According to https://github.com/buildbuddy-io/rules_xcodeproj/issues/84 it appears that cc_test should be supported, so I expected to be able to set //test/cc/unit:envoy_config_test as the test action.

Versions

• Bazel: 6.0.0
• rules_xcodeproj: 1.0.0rc2
• rules_apple: a0f8748ce89698a599149d984999eaefd834c004
• rules_swift: e769f8d6a4adae93c244f244480a3ae740f24384

Additional context

• //test/cc/unit:envoy_config_test is defined here: https://github.com/envoyproxy/envoy/blob/51b4927d215df821bff04d35969eb54cd53d3b31/mobile/test/cc/unit/BUILD#L7-L16
• It's an envoy_cc_test, which is defined here: https://github.com/envoyproxy/envoy/blob/51b4927d215df821bff04d35969eb54cd53d3b31/bazel/envoy_test.bzl#L146-L193
• It defines a native.cc_test here: https://github.com/envoyproxy/envoy/blob/51b4927d215df821bff04d35969eb54cd53d3b31/bazel/envoy_test.bzl#L167-L193

Reproduce the failure from the provided Envoy checkout using ./bazelw run xcodeproj and the //test/cc/unit:envoy_config_test target. Trace how cc_test targets are placed in the generated test_action, using the referenced envoy_test.bzl definition and rules_xcodeproj issue 84 as context. Done means the target can be selected without the XCSchemeInfo assertion.
