perf: Remove telemetry from wrappings of store (backport cosmos#10077) (

cosmos#10170)

* perf: Remove telemetry from wrappings of store (cosmos#10077)

## Description

Closes: cosmos#10072

Significantly speeds up all the GasKvStore and CacheKVStore operations. Now Get/Set for these stores no longer even appears on my Osmosis benchmarks, saving ~8% of those benchmark's times. (Only one of the internal methods for setCacheValue appear -- will try to separately get a PR for reducing those memory allocations if cosmos#10026 is merged)

Talked to @alexanderbez about this on Discord, and he seemed in agreement with the approach of removing telemetry from these stores.

This does technically change telemetry, but I don't know if this is / should be considered a breaking change?
