Gas mispricing in cosmwasm-vm

Component: wasmvm
Criticality: Medium (ACMv1: I:Moderate; L:Likely)
Patched versions: wasmvm 1.5.4, 2.0.3, 2.1.2

Some Wasm operations take significantly more gas than our benchmarks indicated. This can lead to missing the gas target we defined by a factor of ~10x. This means a malicious contract could take 10 times as much time to execute as expected, which can be used to temporarily DoS a chain.
