Aliasscope miss-compile for 1.11+

[vchuravy]

As observed in #652 these kernels behave differently on 1.11+

@giordano notes on Slack that this also resolves an issue he has observed with https://github.com/CliMA/Oceananigans.jl/blob/4265addd082f0462dfd4fc7114b89efa2a420ece/src/Models/NonhydrostaticModels/update_hydrostatic_pressure.jl#L12-L20

So the core of the issue is that :aliasscope seems to be causing a miss-compilation on 1.11+

I haven't been able to root-cause this for Julia itself. But since it occurs on the CPU backend this is likely a bug in either LLVM or Julia.

I see two options:

1. Disable aliascope and thus @Const handling everywhere
2. Disable it only on 1.11/1.12
3. Only enable it when there is an actual @Const
