This commit adds `IndexInput::isLoaded` to help determine if the contents of an input is resident in physical memory. The intent of this new method is to help build inspection and diagnostic infrastructure on top. The initial requirement is to help understand if vector data and more specifically the HNSW graph are in memory. For search use cases, performance drops off significantly if, at least, the graph is not resident. This is not a perfect API, more of a hint, but along with read advice like MADV_WILLNEED may be used to determine perf issues searching vectors -- This is an automated message from the Apache Git Service.
