Check failure happens in SsdFile.h

[yma11]

Bug description

When use AsyncDataCache together with SSDCache enabled, I got an error about size check failure on file_entry_size vs 8M. Here is the whole stack:

@oerling Do you have any idea about this? I think a file cache entry is easy to be larger than 8M, why we limit to this size here?

[yma11]

@xiaoxmeng @zacw7 Do you guys happen to know about this? Thanks.

[zacw7]

SsdRun only reserves 23 bits (out of 64 bits) for size. Maybe we can expand it to 128 bits.

@yma11 what's the loadQuantum size used in the query? Thanks!

[yma11]

It's 256MB. So I need to set it 8M if want to enable SSD cache?

@yma11 that's the current implementation limitation which need to fix @zacw7. We shall also put limitation on the max size of loadQuantum that we support.
