API for --cfg for MetadataCommand

[wcampbell0x2a]

👋 I use this project for zerus. I noticed different output from my zerus and cargo vendor. This is (I think) due to me not setting the rustc --cfg to a certain os during my operation. But I wonder, if there is a good way of ignoring the target field when generating from cargo metadata?

I think for the following, this means I want to ignore the following target and treat this as a required dependency.
"target": "cfg(all(any(target_arch = \"x86_64\", target_arch = \"arm64ec\"), target_env = \"msvc\", not(windows_raw_dylib)))",`

Here is my code.

Eh, maybe this is a cargo issue:

• Support for vendoring on a single platform rust-lang/cargo#7058
• Stabilize -Z avoid-dev-deps as --minimal-cargo-lock rust-lang/cargo#5133
