Fat linking with `subsecond` fails on windows due to CLI command length

[dsgallups]

Problem
The command issued here can be extremely long on windows systems.

dioxus/packages/cli/src/build/request.rs

Lines 1838 to 1844 in b2bd1f4

	let res = Command::new(linker)
	.args(args.iter().skip(1))
	.args(out_arg)
	.env_clear()
	.envs(rustc_args.envs.iter().map(|(k, v)| (k, v)))
	.output()
	.await?;

Windows has a command length limit of 32767...so, projects with many dependencies are likely to fail.

Steps To Reproduce

On Windows, you will need to create a project with many dependencies. This should fail, even if the project is located in the root of the drive.

Attached is output, where I have added a trace for the command to be executed. This is a debug of the Command struct.

• Dioxus version: main
• Rust version: 1.87
• OS info: Windows 11 current stable

Edit:

Jon Kelley has mentioned decreasing codegen-unit size as a workaround 😄

I think the right fix here is to use a "command file" or @file on windows.
