RFR: 8294954: Remove superfluous ResourceMarks when using LogStream

[Casper Norrbin]

Hi everyone,

This PR removes redundant `ResourceMark` instances where `LogStream` is used. Previously, `LogStream` inherited from `ResourceObj`, which required a `ResourceMark`, but this is no longer the case, making these instances unnecessary.

Process:
1. I added assertions to check for resource unwinding in places where `ResourceMark`s were used with `LogStream`s.
2. Ran tests up to tier7 to confirm no unwinding was happening. This helped filter out cases where `ResourceMark`s were still required for other reasons.
3. Manually verified the remaining cases by tracing function calls to ensure the `ResourceMark`s were truly unnecessary.
4. Removed the redundant `ResourceMark` instances.
