infer-tag: Allow user to infer ABI3 and Pythonless

[henryiii]

Two very common needs (see https://github.com/charliermarsh/whisper.cpp-cli/blob/35b8b6115e5b4c25b6357c857daf9e7c2a230eed/hatch_build.py#L56-L91 for example) is the ability to set Pythonless compiled wheels (ones that don't use the CPython API) and ABI3. In scikit-build-core, this is done by setting wheel.py-api. I think the same system could be applied to infer-tag. The proposal is:

Allow infer-tag to be set to a string as well. Setting py3 would infer a py3-none-* wheel. Setting cp311 would infer a ABI3 wheel as long as CPython is 3.11 or higher, and a normal binary wheel otherwise.
