add GPU inference reproducer

[juliasloan25]

Add a reproducer for the Field broadcasting bug initially found in CliMA/ClimaLand.jl#739

This is a type inference error that arises when a function is broadcast over one field and two structs that both have broadcastable extended using tuple. The problem is simplified here so the structs each contain one scalar value, and the called function itself does nothing. The reproducer was tested on multiple different field types, and reproduced the bug on all of them.

• Code follows the style guidelines OR N/A.
• Unit tests are included OR N/A.
• Code is exercised in an integration test OR N/A.
• Documentation has been added/updated OR N/A.
