[HETERO] Add CPU and GPU plugins to tests dependencies if exists

[aobolensk]

Details:

Fix dependencies issue when hetero tests dependent on CPU and GPU plugins fail if ov_hetero_func_tests are built as the only target:

$ cmake -S . -B build -DENABLE_TESTS=ON
$ make -j$(nproc) ov_hetero_func_tests

@peterchen-intel is it expected that HETERO tests require CPU?
As I remember, we worked on clean up of Meta plugins tests to avoid dependency on HW plugins, but not re-call whether it was finished for HETERO func tests.

@aobolensk Sorry for later, I'm trying to reproduce this issue in local,

1. The build process succussed with only ov_hetro_func_test.
2. Run ov_hetro_func_test failed with can not find the cpu plugin.
   Actually the nightly tests need hw plugin in the test, so if u only build the ov_hetro_func_test, the nightly* related tests can not be run.
   The correct command run ov_hetro_func_test (for the only building) is:
   ./ov_hetero_func_tests --gtest_filter=-"nightly*"
   And one more thing, I find another bug in hetro func test in the processing & fixed in this PR, pls try with this changes.
   [Hetro][Func Test] only the nightly tests can use hw plugin #28545

2. Run ov_hetro_func_test failed with can not find the cpu plugin.

True, this is exactly what I see on my side. According to @ilya-lavrenov we should do that on both levels (CMake and tests):

1. If CPU plugin is available then we need to require it to be built first (using add_dependencies in CMake) - this is what my patch does
2. There should be a mechanism in the tests that disables CPU specific tests on gtest side for them not to be failed if CPU plugin is not found

Sorry for the late reply, I have tried on the same environment with the latest OpenVINO (with your patch included). Some tests are still failing due to the same reason: lack of CPU device
