test(transport-h2): disable timing-sensitive benchmark tests in CI

Add @ignore to all 6 tests in H2PerformanceBenchmarkTest and 3 of 5
tests in H2Stage3StreamingTest that assert wall-clock performance
thresholds.  These tests pass locally but fail non-deterministically
on GitHub Actions runners due to variable CPU/IO load.

testFlowControlManager (H2Stage3StreamingTest) is left active as it
contains only functional assertions with no timing constraints.
