Optimized read mode for OPA's in-memory store (#7125)

A new optimized read mode has been added to the default in-memory store, where data written to the store is eagerly convertedto AST values (the data format used during evaluation). This removes the time spent converting raw data values to ASTduring policy evaluation, thereby improving performance.

The memory footprint of the store will increase, as processed AST values generally take up more space in memory than thecorresponding raw data values, but overall memory usage of OPA might remain more stable over time, as pre-converted datais shared across evaluations and isn't recomputed for each evaluation, which can cause spikes in memory usage.

This mode can be enabled foropa run,opa eval, andopa bench by setting the--optimize-store-for-read-speed flag.
