snuba(devexp): Migrate meta queries to use storage direct queries

[enochtangg]

Overview

Now that snuba supports querying a storage directly (as opposed to querying an entity), meta queries are a great candidate to take advantage of this. All meta queries are executed through the metrics layer, therefore these changes will apply to any product (right now just DDM) running meta queries. The main change is switching out Entity for Storage in the match clause of the query.

Testing

This change is guarded behind the sentry option: sentry-metrics.metrics-layer.use-storage-direct-meta-queries and will be slowly rolled out + monitored.
