Added BenchmarkLayerTest class for simplifing of benchmarking

[lohika-denis-kotov]

Details:

This PR adds BenchmarkLayerTest that simplifies benchmarking of single operator. The BenchmarkLayerTest has the following advantages:

1. Reusing single layer test cases
2. Almost no need code for benchmarking single operator
3. Could be add in CI for verifying on performance regression (using Validate method)

Here is the example of using BenchmarkLayerTest:

...

struct GenerateProposalsBenchmarkTest : ov::test::BenchmarkLayerTest<GenerateProposalsLayerTest> {};

// By default benchmark tests could be disabled
TEST_P(GenerateProposalsBenchmarkTest, DISABLED_GenerateProposals_Benchmark) {
    SKIP_IF_CURRENT_TEST_IS_DISABLED()
    run("GenerateProposals", std::chrono::milliseconds(2000), 10);
}

INSTANTIATE_TEST_SUITE_P(
    smoke_GenerateProposalsBenchmarkTest,
    GenerateProposalsBenchmarkTest,
    ::testing::Combine(
        ::testing::ValuesIn(dynamicInputShape),
        ::testing::ValuesIn(min_size),
        ::testing::ValuesIn(nms_threshold),
        ::testing::ValuesIn(post_nms_count),
        ::testing::ValuesIn(pre_nms_count),
        ::testing::ValuesIn(inputTensors),
        ::testing::Values(ov::element::Type_t::f32),
        ::testing::Values(ov::element::Type_t::i32),
        ::testing::Values(CommonTestUtils::DEVICE_CPU)),
    GenerateProposalsBenchmarkTest::getTestCaseName);

@ceciliapeng2011 CI is passed, but PR still needs to be rebased. Maybe it is better to enable automerge for this PR ? Once CI is passed PR will be automatically merged
