RFR: 8369147: Various issues with new tests added by JDK-8316694

[JDK-8369147](https://bugs.openjdk.org/browse/JDK-8369147)

Fixes tests added in [JDK-8316694](https://bugs.openjdk.org/browse/JDK-8316694)

`DeoptimizeRelocatedNMethod.java` and `RelocateNMethod.java` failed because they attempted to relocate nmethods to the `MethodProfiled` code heap which does not exist when `TieredCompilation` is false. Updated the tests to use `MethodNonProfiled` heap which exists regardless of `TieredCompilation`

`StressNMethodRelocation.java` runs for 60 seconds and also compiles 1024 methods with C2. This was causing the test to timeout if the compilation took too much time. Increasing the timeout to 5 minutes should give C2 enough time to compile the functions

`NMethodRelocationTest.java` runs using SerialGC which caused a multiple GC error when trying to run with another GC. Added a requires to force SerialGC
