JNI: Remove `JniMethodFast{Start,End}()`.

Inline suspend check from `GoToRunnableFast()` to JNI stubs.
The only remaining code in `JniMethodFast{Start,End}()` is a
debug mode check that the method is @FastNative, so remove
the call altogether as we prefer better performance over the
debug mode check. Replace `JniMethodFastEndWithReference()`
with a simple `JniDecodeReferenceResult()`.

Golem results for art-opt-cc (higher is better):
