perf(schema-compiler): More aggressive compilers cleanup

[KSDaemon]

This simple fix cleans up references to data schema compilers instances within dispose() method during cache eviction. This slightly improves memory performance by allowing GC to clean up unused memory earlier.

While it won't be noticed in most cases, these changes might be useful for highload scenarios with huge data models.

Here are some insights. Pay attention to the Total Heap Allocated curve.
