[pr/139] RFR: 8326753 Lilliput: OMCache: Use AoS

Tue Feb 27 09:30:19 UTC 2024

The OMCache entries are currently laid out as a struct of arrays. For cache locality layout the entries as an array of structs.

Using structs for the entires also allows for some cleanups. 

Ran through GHA, still need to do some more extensive testing.
