Use |> for moving data to devices

It's more visually suggestive of the data being moved. Also, in an assignment expression, the main data piece/function call is closer to the equal sign rather than the device call.

Summary of Changes

Hello @abhro, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refactors how data and model components are transferred to computational devices within the codebase. It transitions from a functional wrapping style (e.g., dev(data)) to using Julia's pipe operator (data |> dev). This change aims to improve code readability and consistency, making the data flow more explicit and visually intuitive across several machine learning examples.

Highlights

• Consistent Data Movement: Standardized the use of Julia's pipe operator (|>) for moving data and model components to computational devices (CPU/GPU) across various examples. This replaces direct function calls like xdev(data) with the more idiomatic data |> xdev.
• Improved Readability: Enhanced code clarity by making data flow more explicit and visually intuitive, aligning with Julia's functional programming style. This change improves the aesthetic of assignment expressions by keeping the main data piece closer to the assignment operator.
• Refactored Examples: Applied the new piping convention to numerous example files, including ConvolutionalVAE, GCN_Cora, HyperNet, ImageNet, NeuralODE, OptimizationIntegration, PolynomialFitting, RealNVP, SimpleChains, and SimpleRNN, ensuring consistency throughout the codebase.

Code Review

This pull request introduces a stylistic change to use the pipe operator |> for moving data to devices. This is a great improvement for code readability, making the data flow more explicit and aligning with idiomatic Julia style. The changes have been applied across numerous example files. I've found one minor inconsistency where the old style is still present in a modified line, which I've pointed out in a specific comment. Otherwise, the changes are excellent.
