RFR: 8371131: Cleanup Thread parameter in CollectedHeap TLAB methods

Mon Nov 3 09:57:38 UTC 2025

Hello,

The last usage of the the Thread parameter that is passed to `CollectedHeap::{tlab_capacity, tlab_used, unsafe_max_tlab_alloc}` was removed in [JDK-8370345](https://bugs.openjdk.org/browse/JDK-8370345). Following this we should remove the Thread parameter completely from CollectedHeap and all GCs that derive from it.

Testing:
* Running through tier1-2
