[memorylimiter] Add disable_gc configuration option

[vyagh]

Adds a disable_gc configuration option to the memory_limiter processor. This allows users to opt out of forced garbage collection while maintaining logic for data refusal when memory limits are exceeded, supporting scenarios where multiple memory limiters are composed across pipelines.

Fixes #15081
