Reduce precompilation

[MilesCranmer]

The precompilation for DynamicExpressions.jl is a bit expensive right now, especially for Julia 1.9. This reduces it slightly, by removing ^, log, exp, sqrt, abs as precompiled operators, and also removing turbo=true and T=Float16 from the precompilation settings, as I think these are less common settings.
